Make a video series on the health effects of having windows. You need to prove how insane you and Dave Jr are where you are and then how sane you get when you move. I am sure you can manage the lighting problems.
Put up a bird feeder and aim your live camera at it, I think it would be more fun sometimes (sometimes your live feed looks dead because no one is there). Of course it has to be an electronic bird feeder.
Start selling your EEV meter and develop a bench version of it. You need a new place to make/sell it.
Start a KS on your meter (maybe bench version) with a goal that will pay for a new place.
Get Wiki to set up on EEVBlog so your videos would get more hits.
Set up a Electronipedia, that would be central point of all your web stuff and allow others to join it, like a Wiki for electronics (suggestion from another member)
You said it had an outside area. If so sell bricks and engrave them with donors names and line the walkway or wall with them. Can you imagine how happy some members would be to see their names on something in the videos. Name it "The Wall of Support"
This is a popular means to raise money in the US. Either laser engraved or brass plates glued on the bricks.
Put together and sell some guided tours of Australia that includes your garage and workshop. Include the famous Duck boats and tour buses.
Sell some of your equipment and put the new owners name on the front and keep it. Again satisfaction for the buyer to see their names in the videos.
Develop an app to be used by emergency organizations when they need help with anything electronic related. Your forum has good real time response. I think this could be a life saver if done right.
Set up your mailbag, stating that you will sell the stuff to help pay for new quarters.
Set up a web page that links jobs between those that need help and those that need the work, for a commission.
Keep your word from a Apr 1 video and get on the payroll of a test equipment manufacture.
My favorite - more videos on cheaper stuff. Some of your stuff is really over the top for poor people.
Hold Maker type workshops at your new location (thus a larger site is needed). You could video the lessons.
Set up a paid subscription electronic tutorial site. Surprising there is a lack of good ones. PIC32 is sorely missing. Not just one or two videos but a semester worth of them filmed in front of live students. I would pay. So your new place needs to be large enough for holding classroom lessons (at least 12 students). I think you could teach live students and online ones at the same time.
It seems this type of thing peaked in 2012.
So I say you need a larger place to do all of the above
