We have just developed a Wordpress calendar plugin and need someone with a great deal of experience in building tracking systems. Ultimately this plugin will end up being a freely available widget-based add-on and as such I need to be able to track how many people are using the plugin, how many impressions it is getting, how many people are clicking on it, what they are clicking on, and what events are being downloaded (whether to iCal, Outlook or Google calendars). I understand that perhaps something like Google Analytics/tracking codes might be out of the question, but as close along those lines as humanely possible. It will need to be able to breakdown statistics based on what website it is hosted on, OS used, geo-graphic location of users/audience and present both numerically and in graph form, ranging from 1 day to the duration the plugin has been in use.
Also you must be able to develop this on your own standalone site/server as we do not want the development to get in the way of our current traffic.
Ideally I would like the winning bidder to have had prior experience and/or already have a similar developed analytics tool readily made (to adapt) as do not really have the time or budget to have someone code one up from scratch.
PLEASE NOTE THAT THIS IS FOR SERIOUS BIDDERS ONLY!!!
(I will treat any bid quotes left as the final price and do not want any under-bids with PMs telling me it will cost twice the price as I will merely report you to Freelancer and you will definitely not win any of my business)
