It's implied you've come up with a business plan and you state you have sorted out how much things cost though you should probably take inflation into account and your profit margin is likely going to need to be increased to make up for those costs. The other research you'll need to do is supply and demand. Is what you're doing even in demand and if so, how much supply will you need? Will you need a patent for your product? It seems like you've already done this as well. If you do get one... once you have that patent, you could approach other companies and see if they are in the market for your product. They can license it from you, ultimately funding your operation, and allowing you to do more, while also giving you the reputation and customers you'll need. It's a fairly small business investment you seek... YOLO is a good philosophy to have. Think of it as funding another college degree but instead, it's your actual business. You have two options with this: take the risk or don't at all. You'll be more upset with the latter, especially when someone else comes up with the idea and runs with it. You'll only wish you did it. If you succeed, you'll turn your small investment into a fortune. If you don't succeed, you'll just owe some money to the bank. Another day.. another dollar.. we've all been there. If you can't find business partners in the beginning and are just seeking the loan, I'd suggest looking around your town for a credit union or a small bank who can probably give you a better interest rate than most. I personally stick with my Discover card that often supplies loans with 5% - 6% interest, which is often better than most, especially in this economy. It is rare, but there are bank/fund/credit companies that value loyalty with good credit out there. A search of "small business banking" and "small business loans" after you've established your LLC may also help, with banks giving you a pretty good deal just for being a new business. I hope this advice helps you somewhat... but you do sound confident in what you're doing, so do it. Remember.. most of the greats started out in their garage... and got help from their parents. They started somewhere, believed in what they were doing, even when the rest of the world couldn't even grasp the concept. So get going on this opportunity!
