I am 21 years old and have a Pretzel company with 2 food trucks running. I am looking upgrade all of our equipment to be able to handle the amount of wholesale orders we are getting. I have had multiple friends, older guys I know and other business owners tell me when I am ready they would be happy to invest. Is this the route I should go or would it be better to get a SBA loan?

If I went the route of asking for an investor how do I go about asking them and what is a reasonable valuation for a business that is profitable in 8 months and with net over $150,000 our first year.
