As far as the business plan don't get too hung up. Just get a template online and fill it out the best you can and as honest as your can. If you need a loan you can clean it up later. A lot of ideas never make it past fruition because of the fear to dot i's and cross t's. Sometimes just starting can help you figure out what to do next. Don't be afraid to fail, most business owners have several failures under their belt and are better for it.
If I were you, I would test the market as if the company had already operating. Give it a shot and see how many leads can you get, ask around about your product/service and see who would need it the most and how much would they realistically be able to pay.
If everything is good after a 7 week trial, go with full speed ahead. That's what I would do if I were you.
Certainly start in a limited way, don't over-reach yourself or your finances. Keep expenses and outlay as low as you can initially and be prepared to work incredibly hard for a limited income initially. A good business plan is essential if you're looking to get a loan to start you up but there are plenty of online tools to help you complete one professionally if you have no experience in preparing one before.
