Autosurf Website Development

I would like a auto scrip same as 12 daily pro. I am summarizing for the script to have these features: - full functional Autosurf script - site news - site statistics - auto upgrade via egold - Mass payout with egold - auto added referral commissions - show payment pending at history when the upgrade expire until it is paid - pay to processor that member upgraded with - members can only have 2 active upgrade packages at one time (able to choose more then 2 by admin) - auto deduct member cash balance when upgrade expire and admin will get notification and also it will show as pending in members history - FOrum for members I need a admin to manage whole website & users. I need to know about the maintenance charges after dwebsite development and transferred to my server. I want this whole project to be done as soon as possible.
