If you have the resources then why not, but i believe your budget wouldn't be enough. 1k to 2k USD i think will do, not including the advertising and promotion.
you should hire specialist for this in order for your gambling site to be a success. help of experience ICO people will be a good start for me.
Yes budget is low. Script is almost ready.
We thought and planned to have own token and start ico but it will happen only and after launch and successful fully launch of site.
