Dear Sir,
I have read your Project Description and understand the high level features explained by you. However, before I come up with our understanding, do you have more detailed requirements, some reference/example websites URL or you can drop me a message thru' Freelancer PMB, so we can discuss further & come up with our estimate in terms of time & cost to move forward. Because without having detailed requirements, we cannot estimate it.
I really need more details on the Chat function, whether you will purchase some OpenSource Chat for us to integrate or you want us to search some chat module?
About the leaderboard, what kind of features you want in leaderboard?
Look forward to hearing from you.
Regards,
YK
