I really like the layout and the design but you will always have a problem selling your platform/script to casinos because there are security concerns and there have been in past cases where the casino script had bugs and the house leaked money. Most of the casinos for that reason prefer their own developer.
But good luck and you might find some interested casino owners who want a ready-made design and script. Maybe you should list all that you are selling in a better manner, like what exactly does the buyer gets: script, support, etc I am not aware of all the possibilities.
By the way the design looks very similar to the one at bcgame so I hope it's not copied but only inspiration was taken
