502880 Oscommerce/creloaden payment process

Hi All, For our website (google name in attachmnet and its the first hit) we want to have a one page checkout system. In the modules in admin there is a 'one page checkout' option, but it is not active at the moment (and i do not know if we can use this) But we want to simplify the payment process, it currently consists om 7 steps.... We would like to bring down the user details, shipment option and payment option on one page, now its 3 separate. Who can help? We need the project fast, hens the 2 day bidding period. thanks in advance
