I architect, build and deploy custom web applications for a company using MS Sql Server, IIS, and .net. As I look to open my own consulting business I find myself confused as to how Microsoft prices licenses for instances of SQL Server and IIS. MS web resources on the topic are very vague and require a consultation before they give any prices. Can anyone give me a high-level idea of 1) Which instances of what require licensing and 2) basic cost structure. Just looking for some ballpark clues to this...
