We need two rounds of wire framing done first round is to take existing pages and build wire frames and 2nd is some new pages to be created. After I will give some edits and those need to be incorporated after you do the set.
Wire frames should be built with Gliffy - Gliffy is like Visio but Online.
I will expect a sample before hiring.
Also if you have used Visio or other tool please tell me
