Can anyone help me out?

I want to buy rdp and I want to get a suggestion for the best provider with best prices.
I don't want slow, I will buy mainly for browsing.

And also have some question in my mind,
1. Rdp will be anonymous? I mean, what I do within the rdp does the service provider can know?
2. Can I change the password?
3. What is admin access / admin rdp?
