I want to deploy and publish my first asp.net mvc 3 web application at my client side (the client is a small office with 2-4 employees that need to access the application) , currently i finished developing my web application using the free Microsoft Visual Web Developer 2010 express and the free SQL Server 2008 R2 Express database . So my concerns are :- 1. The free sql express database that i am currently using have a limitation of 10 GB i think So i want to buy SQL server for small business to remove the database limitations. So my questions that i need help with them are:-

**1. If i use the sql server for small business then will my web application have other limitations on production i am unaware of ?

2. Will be using SQL server for small business my right choice? baring in my that the system will be used by 2-4 clients only?

3. How much does “approximate ” the sql server database will cost in US dollars?

4. Are there any other software that i need to buy to be able to deploy and publish the application on intranet and the internet ?**

Appreciate any help Best Regards
