sponsors will come and go i was a sponsored Mx freestyle for about 2 years through fox and shift (mx brands) and to be honest it was a pain in the arse ive always done things for me and when you have sponsors you have to kind of bend to what they want you to look act and talk like if you love what your doing they will come its just a matter of time i work with a guy who has fought at the top level in australia (CfC )and got nothing and he's 4 and 1 except a few boxes of tap out gear in time all good things will come don't let is discourage you just keep at it i'm sure you will get some someday
