Online OSCommerce store

Hello all, need someone to help with set up of online store; we currently have Template Monster #18596 which is Oscommerce 2.2 rc2. Need someone to modify template for us, and get our webstore up and running. We would also require provider to explain us basics of how uploading of new producst and general set up works. If there is possibility of porting this template and setting it up as Wordpress store than we would also be interested in that option. We currently have hosting, but we can change it if necessary. This is a small project with very limited budget as we are setting up online trading and have lots of other expenses at the moment. Looking forward hearing back from you!
