friends are great you just have to know how to use them.

since you doing skateboarding and snowboarding they might be buddy buddy with a shop owner or someone who can help you. also ask them if they will help advertise for you. they dont have to know alot about the business. i am not anywear close to an expert or even experianced on the business and neather were when you start up till you have gone through selling shirts several hundred shirts unless you were in it before. (not tring to put you down. hope you dont take that the wrong way).
i am using some of my paintball buddies to help me out. one of my friends knows the owner of are local store so he is going to set me up with a meeting. acouple of my friends know some big name player who i am going to talk to for sponsorship and more contacts.
it just takes one person to know somebuddy so you can it off big. i know what you mean tho by when you say your friends are tring to help in the wrong way just dont totally shut them out.
my 2 cents
