Hello! I just googled for dbo and found this here 
It looks very good and pretty official in my opinion, selling founder packs, multilanguage
But this project is a fan project (private server) right?
The company of the game is in asia and idk if they would sue you, but have you thought about that? :O
What if they do that?
If you sell founder packs and they sue you, you would have auf pretty big financial problem..
Looking forward to this project!
