There is absolutely no reason you should raise money from outside investors for this type of business. You grow this business with sales, with more customers paying you for your services. If you think, yeah but if I had $500k of investment I could hire two sales people and two more techs blah blah blah then my guess is you will ending up wasting a lot of money and failing. Grow your company with the people and skills you have. Be frugal. Put cash in the bank... then when you're at the breaking point, hire a new person.. rinse and repeat. Then you still own 100% of the company, you have cash in the bank and can eventually afford to take some risks on your own products.
