PHP bug fixing and updates

Will need a bug fixed in our php script - whenever the user tries to login, there's a login error the first try the user signs in, the second time it works. Will also need to send users email when they signup Will need to integrate moneybookers and paypal (almost integrated) and make them work. Will need to update the user account - putting a "balance" feature (adding or withdrawing money). Further details will be given under NDA to the winner. You have to be able to work full time on this and get it ready as soon as possible. People who can do this in 3 days (except moneybookers integration) will get a $200 bonus. So the deadline is 3 days and the budget is $600. If you move fast enough and you do a good job, you will continue updating this project for at least 3 months.
