Sports bet website

Hi everyone! 

I want to create my own website for sports bets and I found only one company which can help me with the development process (https://eulerr.com/project/cat/web-startup/), is there any other companies with a good portfolio or famous teams? At the same time, Eulerr has a nice price and a good team, but I just want to compare and see other offers before starting. 

Thank you!

pm me.
