hi there i used to be a LoL player before and have a good knowledge of how the game works.
I would like to offer my services to developing the site.
I was never a pro player just a casual usually playing with friends or bots.
My son still plays it, now a days i play a bit of dota2 but really dont have much time for it now.
I can see that you want to set up a account selling site, with paypal integration?
I can definitely help with it. I do have experience with paypal standard payment gateways.
Hope to hear from you to discuss further, we can set up some mile stones and deliverables.
have a good day.
Nikhil.
