Hi,
I have 4 groups on facebook. All of them are made a while back and they all allow you to send mass messages to all members.
couple of them have more than 2000+ members too.
I can work with escrow money, you can put money in escrow, send 50% upfront and 50% in escrow, and release it after you get everything in your control.
Price is $200 each group.
Again, all my groups will allow you to mass emailing to all members.
thanks
