PHP Script - Ranking System with Reset fuction after 7 days

Hello, I have an game server that uses MSSQL. I'm looking to someone to develope an PHP SCRIPT TO : GET ACTIVE USERS (Can be acessed from last login table) When users are active, script will get PVP (When player kills other player) (Can be acessed at User table). SCRIPT Will count pvp from active players of last 7 days. And will make a ranking. After 7 days, script will reset and start again the count. (new ranking). I need it to be displayer at my site. The reset will not be at pvp table sql of server, but only to display into site, each 7 days script will need to calculate the last pvp and start a new count and ranking it. Example : Player X have 1800 pvps into server table. When the week start php script will count as 0 (but only script, not the sql). If player into this week made 150 pvps, sql will count as 1950 ; and php script will count only 150. After 7 days, it will be reseted and start again. I already have a rank script [login to view URL] But i'm looking a new to be counted as weekly Can you do this job? If yes, whats your price? Thank you!
