I realize you may be new here, so instead of being a dick I'll explain something to you.
Offering to be a mm is a good deed, but no one will trust you. Have have to be known in this community to even be considered. I'm sure you can understand that no one is going to have a new member with little to no reputation having to do a deal. Your best bet will be to stay on this site for at least half a year and build up your trustworthiness.
Hope I helped clear something up!
Sorry to post a little off topic, OP
