Hey there everyone,
As usually things that work out are not cheap or simply easy to access, meaning as good at it sounds the result is not what you want from this guy. So if still wondering if this guys is for real or not, i can tell you he is not or then just conveniently disappeared from the face of earth when delivery was supposed to happen.
In short, he is 99% sure scam.
Let us know if this works out. I communicated with GambleDev on and off for a week or two about a site idea (he was always quick to respond), but he hasn't responded to my latest email confirming the address I should send his payment to. The wait has been 5 days, which could be explained by him fixing the other site, but that's obviously not great customer service and something to think about if you ever need technical help from him after your site is made.
That said, I don't think this is a scam since he would be quick to confirm the address and receive my money, but I could be wrong. I'm going to wait and see the other responses on here, but I'll also provide an update if I hear back from him and try to make the site.
