Hi
Please do not take this the wrong way. Loosing a father at your age (or any age) is not at all easy. There's a ton of emotion and now a bunch of worries. Rather than beating around the bush, about the business. There are some things you need to check out very soon:
The business likely has obligations and they need to be taken care of. I don't know if this is a one man shop or a 500 person enterprise. Some of the stuff below is slanted towards the smaller end of things since I simply am guessing.
1) Do you (yes you, it's yours) have any customer property? If so can you identify it? It needs to go back to it's owner. I'm betting you do have stuff in for repair.
2) Does the business have employees? If so, have all of the various tax payments been made for them? Who will be supervising them for now?
3) Does the business owe rent on any buildings? If so, when is it due? (hint: is there a storage locker (that's often overlooked)? )
4) Does the business owe money to suppliers (or utilities, or ...)? If so when is (was) it due?
5) Is there insurance on the business? How long before it renews?
6) Are there any financial records for the business? Is there an accountant? Is all of it up to date, if not can it be brought up to date?
7) Taxes are normally paid quarterly. There should have been a payment made at the end of March and June. Were they made?
That's the immediate stuff. It has to be done. It needs to be done regardless of what happens to the business. It can't wait for another six months.
Now for the longer term stuff:
1) Was the business making any money? If so was it making enough to live off of? Again, I simply know nothing about it so it's a question to be asked.
2) Can the business expand so it *does* make enough to live off of? (If it does not now).
3) Have you sat down with an accountant and verified all of this? (= have you missed something?)
4) Is the business something that could be sold? If so for how much? (= what is the business worth?)
5) How much work will it take to keep the business going?
Assuming you can get a handle on the stuff above, you should be able to answer "how well does this pay?". It could be an 80 hour a week job that pays $25,000 a year. With your degree you should be able to do better than that. To me, if that was the case, there would be no further need for evaluation. Let's say it pays well and it's an ongoing thing.
The next question is --- do you have any interest in doing this at all? That's not an easy thing to answer. It *does* need an answer. You will be in a people facing business. Your life will revolve around customer contact and direct interaction. Some people thrive in that sort of setting. Others really don't. It is *not* easy to figure that out. My advice would be, unless you are really fired up to do this ... don't. There will be good days. There will be bad days. You need that fire to get you through the bad days.
If the decision is to keep on, then you need some training. It's going to have to be part time. Shutting down the business for a few years is *not* an option. 20 hours work / 20 hours school is likely the best you will be able to do. You need at least one course in business basics. You will need a number of courses in electronics. Get that done now. It will only be harder to pick up later on.
The other branch in the road is to sell the busies....
Many decisions ...
