I am toying with the idea of buying a 14 foot flat bottom and adding a carpet casting deck on front with a poling platform on back. The poling platform will mainly be for added height to help with sight fishing since I plan on having a trolling motor up front.

Anyone have a skiff or john boat they use for fly fishing freshwater? Pics would be helpful since my searching on the net has not turned up much.

Look into a Carolina Skiff

Yep
Lots of cheap used ones
