Trustworhy Agents in the U.S.

Hi guys, first post and to begin I just wanted to tap the UG knowledge base with a quick query. Long story short I am looking to find out who the trustworthy agents are in the MMA world in the US.

I read a thread the other day by MMA Portraits in which several 'good' guys were mentioned, so I wonder if anyone could stick anyone theyve dealt with and found to be trustworthy in here?

Im concerned by contacting supposed agents on email addresses listed on their websites and, since I'm new to the experience of contacting agents, finding out that the person I am in touch with is actually a scammer.

Thanks for any help in advance.
