Actually, to add to the above post... the internet is, believe it or not, almost useless for finding grants for schooling. There is a lot of information, but it's not concise and you can spend literally months just trudging through the links and reading to end up with little actual information on WHICH grants to apply for. I am a development coordinator and write grant proposals for my (part-time) job. I work with grants, grant-writing, foundations, etc. and get people asking me about this all.the.time. Actually, most of the grants that would work for your situation would be more local. If you go to your library (assuming it is larger, not a very small community library that has a limited collection), they should have a collection of books on scholarships and grants, including grants that are offered locally, statewide, and by category. These books can be browsed, or these days they usually have CDs that come with them so you can search based on a set of criteria. I would go to your library before using the internet.
Now, when you say "bike", to me that means bicycle. Sorry, it's just my background (former competitive cyclist). I don't know if you mean bicycle or motorcycle. If it's bicycle, I would suggest looking into having your dh apprentice at a local bike shop instead of school. That would take longer and he wouldn't get paid for it, but he wouldn't be spending any money, either. If by "bike" you mean motorcycle, well... I have no idea, but there may be an apprentice option for that, too. I know a lot of my old friends would just hang out in the back of bike (bicycle) shops and many of them went on to open their own shops.
I would not go to ANY program that is not accredited. Good Luck!
