Once upon a time I owned a "247" prefixed domain and in the .COM! I dare say, too, that mine was more valuable/relevant (word after "247") than the second part of your domain, being "casino".
I allowed it to drop!!
Point is, this would have been a VERY long-shot, even in the .COM! For a new, unproven ".BIZ" ... like it or not ... at this stage of the game, DrWho is correct (whether he remembers it or not)! Sorry.
Good Luck.
