Well I am a member of this social network site I guess you heard of it already but you can only PM it's member about your offer regarding this what I advice you is to be friends with them first so they will come to trust you and want to join under you the site is called Platinum Lounge. You are a member of UDM right why wont you start there instead. or even in mylot there are lots of social site available but I guess it would be better to do your offer at mylot. Thats what I think.
