Do I need .NET or SQL License?

Question

Hi,
I am a web developer. I use ASP.NET 2.0, C# and SQL 2005.
Recently my friend approached me to develop a website for him in .NET.
At present I am working in a company and I don't have a license but the company has
licensed copy of .NET2.0 and SQL 2005.
In order to develop  a .NET web site for my fried what all licenses do I need to get?
What is the cheapest option?
Thanks
