Build an Online Store

Hi I'm looking for a wordpress plugin that adds a calendar booking option to this package for easydigitaldownloads(EDD): [login to view URL] The EDD Marketplace bundle does everything I need EXCEPT new users aren't able to select a date and time (they can only sell digital products). Basically I want users to be able to sign up to the marketplace (using the plugins provided in the bundle) and sell there services via appointment (rather than selling their digital products in the marketplace). I am looking for you to build me the calendar add-on. Appointments will be sold in 1 hour blocks and each user who signs up should have a calendar assigned to them automatically. On their profile page they can select days and times they are available and those days and times will show up as available for purchase in EDD through the website front end store. I hope this makes sense and if not please ask questions and I am welcome to suggestions. I need someone who can "grab the bull by the horns" so to speak. Generic replies will be ignored. Thanks for reading :)
