Not sure if you got the point we are looking to buy the whole system and keep developing
Yeah no one on here is just going to toss forward all of the information related to a site which cost a massive amount of money to make (in regard to the frontend, and the backend) If you want to pay for someone to code something go find someone, people on this forum aren't mules that are going to find things for you and work for free (things that not everyone understands)
Find it yourself bud.
