I'm not sure you're going to get many up front offers based on pure trust.  That is if you're still looking.  After all, if I said that if you used my referral code I promise to give you a 50% cut of what I get from your earnings, would you believe me?  I certainly don't, but that might be because I know me too well.  If you do decide to sign up, all I can really offer would be gratitude.
