I spoke to Nadav and Matan quite a bit and ran into the same obstacle.
In order to do a reskin of the casino they want the affiliate to pay for the artwork and design which is approximately
$2500 – $3k.
I thought this was unreasonable to ask a webmaster to pay to promote their casino. Had they provided the design I would have probably given them good exposure on my network, but they simply wouldnt budge. Penny wise, Pound Foolish.
