Is it expensive to for US$1,500 per man day for a typical Microsoft based solution implementation in US?
However for a One Man Business that requires general service it's way too expensive.
I don't think company will charge US$1500 to a one man company. I think it more or less charging for solution implementation, such as email, portal or directory.
What is the normal rate for such service in US? Isn't there a standard fees to charge by a professional?
I do Security Work for Banks and you had better believe that work is charged at a decent rate.
When I do similar work for small business I charge a lot less.
