10315 small php modificitions

well i got some egold games (each one are individual from another one) around 10 games so i want them to look one! 1. top frame with my logo and a small image of each game below it. a welcome message in the index. 2. this is the most important: when a user arrives to my website with a referral url this referral number must continues to all games (the current situation is a link with the referral number but it went straight to the game and if i change for another nothing will happens) 3. check for security breaks in the script, backdoors.. make it secure as possible 4. the hardest part: the winning odd should be calculated as this: If his potential win does not go over the 75% of played amount the game is random and fair, but if it breaks the minimum margin of 25% then he will lose that round ( for example 9 players played before, 2 won and 7 lost, They each played 1$. That means you have a profit of 5$! if the next playes plays 1$, in case he wins it does not brake the 25% profit margin, so the script decides randomly if he wins or not! But if he bets 3$, in case he wins he will breack the minimum 25% profit margin -he would win 6$- so the script will make him lose ). you bid tell me that you can or not make the 4. 5. make the entire design plus 2banners normal size and 1banner 125x125 6. install it 7. the payments are already automatic but confirm it please its a easy job so i hope so see really low bids thank you ps. my goal is to be like [login to view URL] without the batch thing
