The guy above me gave good advice. Find out where your local economic development group is located in your city and call them up. Somewhere in your town, there is a local angel investor network. Track down their spokesman/woman.
First thing's first....
There are four places to "get money"......
1) Government/SBA
2) Bank
3) Institutional Investor
4) Angel Investor
To complicate matters....the type of business plan each group likes to see is a little different and spun in a different way. Not all business plans are the same.
I'll jump to the end because I can write all day on this boring stuff. Go to your angel investor network for something like this because the amount of money you need falls right within their sweet spot. $50-$250k range.
When you research how to do a business plan, make sure it's focused on strong research for your area/region and tie that directly to return on investment and time frame to do so. NOTHING else matters. NOTHING.
The purpose of a business plan is to show someone you have a clue--- but on top of that for a potential funder to calculate how they will get their money, how soon they're get their money, and what the investor's exit strategy is (equity/loan, straight equity, maybe a combination of equity position and then once you pay them off, they keep a small %).
No matter what, if you ask for an angel's money -- no matter what you put up, you're sure to own less than 40-50% of the company....no matter how awesome your concept / plan is.
In my opinion, and I don't care what anyone on this board says.... a business plan's value is the fact that you actually go through the process to do it so you understand all aspects of the business. After that, it's ONLY value is to convince an investor you can and will pay them back, and what they get for doing that. It doesn't help you run the business-- you should already know how to do that.
As soon as you open the doors to the business....EVERYTHING changes, EVERYTHING needs to be adjusted, what you thought you knew is no longer relevant. It's like a war plan... as soon as the bullets buzz by your head, it goes out the window.
Some people spend months and months writing and revising business plans. If you let it, it'll be a never-ending process. Be CYNICAL with it and know the purpose of it--- and write it as if someone were asking YOU for the money so you'd know what you'd want to see. Don't ask the bank for help. Find a local certified investor who you can pay on the side to consult with--- someone who can help you with the plan. People with $$$ know how their friends like to read business plans----NOT the bank or government. Page 1 was a letter thanking the person for reading it and a paragraph of what i was planning to do.....Page 2 was an executive summary of the money I planned to make, the money I needed and what I was giving up. Get right to the point early.
Hope that helps.
