You are right that members here trade "reputable" accounts...
You need some kind of vouch in order to sell here.
Your 50% upfront rule isn`t very trustworthy.You can receive the btc and get away.
Maybe you can use escrow for the upfront payment so the buyers feel more secure.
The escrow will release the payment after you finish mentoring.
Just a suggestion...
Would have no problem doing that.
I really don't think people are aware of the actual magnitude of earning this will make them.
Anyone with a altcoin site that can be any kind of site as long as it looks like its set up and not empty.
For instant a gambling review site even...
