I don't think anyone said that some "hobbyists" don't have the skills you listed. You missed the point.
As a side note, I don't think you're going to find that skill set in a student. I can't speak for Universities in Australia, but in the States, it's common for a EE grad to have very little hands on experience. I see a whole lot of student's senior projects made with stuff cobbled together from Sparkfun - all hooked up with jumper wires.
And if you do find a student, then perhaps they could do a summer internship, but a full course load and working up to 30 hours a week? That's slim pickings. But....Maybe if they are required to an internship as part of their studies, then that would work. But that's going to be even harder to find. Why don't you go to someone of the local universities and ask? Surely they would need to 'vet you before they can sign off on you being part of their education. They may even underwrite the whole thing. (Also, they usually have job boards you can post on) - that would be where I would start.
Anyways, there some helpful suggestions for you.
So that leaves you with an advanced "hobbyist". If you can find someone with the skill set you listed, doesn't need money, then more power to you I guess. (ya cheap bastard!)
Maybe the job title should be "Wanted: Nerd that lives with his parents, doesn't smell too much, won't take up my time, and willing to work for peanuts."
I have to agree. Personally I have 3 associate degrees - computer, electrical, and electronics engineering technology degrees, and a BS in Electronics Engineering Technology. I've won a national engineering contest from one of the largest semiconductor manufactures out there. I've done private consulting doing digital design engineering services (design, prototyping, PCB layout, Auto CAD 3D Layout, testing, and firmware development - assembler code not C). I worked with finding suppliers for PCB board production, as well as parts and supplies. I am fluent in web design, and network setup and layout. I've done work doing Indy film production, from camera operator to lighting design and programming, to stage and set building. Also for the film work, I designed and built any production automation devices or other technical props where things move (think electronics and the such, to things like squibs for bullet hits and simulated gun fire hitting objects, as well as animated figures). I was heavily involved in the editing of the digital footage as well.
Still my current employment is outside of electronics (I work in mechanical maintenance currently), and as such I would consider myself an electronics hobbyist as I do not currently make my living doing engineering work.
Would I qualify for your position? I would surly think so. I don't do much PC coding as I don't enjoy it, and I would rather do my embedded code in assembler than in any form of C any day of the week. Yes, that means I have less portable code. So what? I'm not designing things to move from controller to controller, I'm designing things I like to build. I can program in C, but resent to doing so.
I've put in the time and practice to learn these things. I've been interested in these topics since grade school, and knew what I wanted to do as both a job and a hobby since middle school. I spent the money on my own lab starting in High school, and by college I had a better analogue and digital lab than most colleges have. I've spent a ton of cash on both my own lab, as well as my education.
But here is the bottom line - do you really think the skills listed above should pay less then a sign flipper on a road crew? Last time I was working in the electronics filed I commanded a very nice salary, in the mid-low 6 figure range (USD, not Peso's, Yuan, or Iraqi Dinar).
If you want to pay someone an interns pay grade, then I would expect you will have a hard time finding someone with all the skills you have listed, willing to work for peanuts. Even if they are "just" an "electronics hobbyist", if they have all the the skills you have listed, then I would expect they would want to get paid fair market value for their knowledge and the skills they bring. What you are asking for is a junior engineer, a programmer, a video production assistant, and a shipping clerk. What you are offering to pay is peanuts.
I would point you over to "The Ben Heck Show" - you know the guy who made the funny barn yard animal toy play sound bites from you. He has 2 people to help him in his shows. One for video production and all around general non-technical helper, and another intern with some technical skills. Both do some very light "on-air" work. And I doubt that either works many hours a week. While I do not know the guy, I would speculate that the technical helper would not qualify for your job description, nor would he work for less than a sign flipper.
