Tracking capabilities for the widgets is a huge bonus, so please describe experience you have with integrating tracking technologies. Also, if you have additional platforms that you could support, please note them in the bid. If you can support any special features please note them in the bid. We are willing to work with the developer to resize the GUI/graphic and supporting CSS code. Our primary goal is to get the application into the above mentioned platforms with the highest level of integration. Don't Bid Outrageous !
