You are freaking joking, or what?
•ASP.NET MVC 2 or higher •MS SQL 2008
R2 •Silverlight 4 and WPF (xbml)
Skip the Silverlight 4 and WPF part - this makes ZERO sense. Silverlight and WPF / xbml are client side technologies. Hosting has nothing to do with it, except providing MIME types, which are user configurable in any reputable host anyway.
•Team Foundation Server 2010
Ok
2.Price must not above $10 per month (pre-paid for1 or 2 year is ok if cost
per month is not above $10).
Ah? ** (censired I* word for not being politically correct).
Sorry. Did you look at the prices of TFS PER USER? No, your (unpaid) licenses are not transferable. The provier needs to use SPLA, or you need to proove your licensing (and even then - 10 USD per month for THAT monster - no way). Unlimited users heck, even 4-5) are not something that can be offered for that price per user by any logic. The license cost of TFS ALONE is higher than that, and TFS is not a low resource system
Your request is one of "living in a dream world". You won't find any business willing to pay for the priviledge of serving you. On top, proper TFS 2010 hosting also needs a lot of SQL and a Sharepoint site (for publishing documents and reports).
Let's see
Just as idea: VS Team Explorer Everywhere alone is 11,22 EUR (about 13 or so USD) per user per SPLA price list, which is provider purchase price. VS Team foundation user pricing is 19 USD per user per month - that is about 25 USD. Again, PER USER and PROVIDER LICENSE PURCHASE.
Any crazy ideas why he should offer you X users for 10 USD when he pays more PER USER just to get the license?
Some offers:
TFS Hhosting, like per http://www.praktikhosting.com/ - pack of 10: USD 65 (!) PER USER PER MONTH. That is for ONE user 6.5 times your wannabe offer.
Another one: http://www.teamdevcentral.com/hosted_Team_Foundation_Server_TFS_pricing.aspx, down to 150 CAD per user per month.
Hm, when you find someone - I look for a guy to rent me a Ferrari, including fuel and insurance, unlimited km, but I only want to pay 500 USD per month. Tell me if you find one. Unrealsitic? Same level as your request.
