How hard is that to start service like this?
 

Dumbest idea I've seen in a while... buyer has to send a check to Zilra, then wait for the check to clear, etc... $25 withdrawal? :1orglaugh you might as well use an escrow service, or bitcoins or dozens of any other more thought out payment services...

or am I missing something?

You are.

Their Payoneer story is the key. I have had that experience myself.

The key idea is remote freelancers can get paid by US clients who can send wires and ACH.

I had a word with them today and asked if they tested withdrawal to Payoneer debit card ( which is basically a US bank account ) - they said they haven't tried yet.

But in general that was the key point to make it work.
