I want to do business in the field of gambling.

[Nikos-Pap]

My search on deciding how and from where should I start my business lead me to this (and a couple more forums). As a pro poker player (in casinos around the EU) I think it's high time for me to put all this hard-earned (and costly) knowledge to good use. But there are numerous casino platform providers out there, so I am afraid whether I might got involved into a scam or sometihng like that. The nature of the job is such that makes it attractive to opportunists - so I would like your knowledge on to the matter. Google is always my friend so I Googled and came up with the following results
-https://www.playtech.com/ (I guess they are the leader out there)
-https://everymatrix.com (what about them?)
-https://www.betproviders.com/ (I have contacted them and had a talk with the account manager - they do appear to be legit, any prev experience?)
