Migrate from OScommerce to EC-shop ecommerce

I have sucessfully installed a new EC-commerce software template. However, I do not know how to move the current OSCommerce database to this new EC-commerce(EC-shop) site. The structure of OScommerce and ECcommerce are different. What I need is somebody that familiar with EC-shop software that can help me to transfer the current database(SQL-size less than 3mb) and setup configurations that make the ECommerce system works. Please refer attached pictures for more details. I am looking for experience expert that invlove the jobs: 1) Export customer data, order data, products listing data, etc from Oscommerce to EC-shop. All products that currently listed on oscommerce store must be listed in EC-shop. 2) Export the same customer logins that they used to have from Oscommerce store. 3) Extract & export Oscommerce - "who is online" module to current EC-shop. 4) Mass-mailing and other setup & configuration that involve to make the system work. 5) Modification of template: Some parts of the EC-shop display are not in English. I need non-English display to English so that everything will be in English. I will be able to help on images editing, if needed. 6) Display order record on paypal. Currently the EC-shop paypal module only shown order number in paypal record. I need order record such as item, price, discount, etc to be shown in paypal. 7) Setup facebook link in EC-shop so that user can click "to be fan" easilly. I prefer to develop the new EC-shop store on a test server first and after make sure everything is running the way I want then switchover the EC-shop store to my current website that running oscommerce. Successfull service provider will be chosen to continue my next small-project as well.
