You have received some good advice here, it would be in your interest to set back and think about you have read on this forum no-one here is trying to sell you anything, but some one you know is trying to sell you a wash, keep in mind they are the salesman and
you are the customer.
If you want to open your own business do the research and get all the local info. you can get, because after you open this business no one is going to hold your hand you will be on your own then.
I wish you the best.
