Build a Website -- 2

I have a business directory website (work in progress) created with listify wordpress theme. I need somebody to help me with the following customization 1. Install and customize a multi vendor or marketplace plug in to enable listing owners to sell their class / events online. Some details about the features required: a. Listing owner publishes class schedule and fees on a calendar format. (e.g. Please see example at [login to view URL]) b. Listing owner can offer free class or deadline for dropping class for free c. Subscriber can view class calendar & price and enroll through payment online c. listing owner can set number of students per class. "Inventory" (spot left) will be displayed on front end. Class enrollment is closed when enrollment is completed. d. Listing owner can manually close a class' enrollment. e. Visitor / subscriber can filter class calendar 2. . Create backend dashboards for listing owner, class subscriber and admin. In addition to all of the available features , user needs to be able to a. User view enrollment list b. User sends emails to listing owner from dashboard c. Only enrolled user can rate a class and review a class from dashboard d. Subscriber can drop a class or require transfer. 3. Enable user to submit a listing for multi location. Current theme only supports single location per listing submission. 4. Make event listing automatically expire after "end date". Current theme doesn't support this requirement. All listings' expiration date is preset by listing period. (e.g 30 days, 60 days...etc)
