Change VB.NET access database application to sql express

We have a small application made in VB.NET ( 2005) which uses access database. We need to convert application to use MS SQL EXPRESS server. Original application was made with DOT NET Frame Work 2. What we need is to convert application to use SQLServer Express database. (SQL EXPRESS 2008 Preferred) following is required: 1. Convert Access database to SQLEXPRESS server ( Which is few min job, it contains only 4 tables and 3 are only used in project). 2. Make changes to Application to use SQL server database. ( VB DOT NET 3.5 preferred) We will provide full existing source code. After conversion application should work exactly as it is working now. If you can not convert we can look at an option of creating it from the scratch. Money will be paid only after it is fully tested by us upon delivery of executables. ( testing period will not exceed 10 days), you will give us new source code after money is paid. We will provide executable to some of selected bidders to let them know more details about project. Thai Coder with English language skills preferred.
