WordPress web developer with extensive experience of CPTs and User Roles

We are developing a nightlife directory called Club Hunter.

Club Hunter is a nightlife guide, listing venues, events, special offers and lots more in local cities.
You can get more information from our landing page here: http://club-hunter.net.

We have created most of the system, but we are having issues with the venue management system, which will essentially grant specific user accounts access to specific venues.
This means that venue/event managers are able to maintain their own venue information and add events when they need to.
The Venue and Event custom post types work fine, and are making use of the Advanced Custom Fields plugin. However, we are trying to find a way to assign specific Venues to specific accounts, so that they can only access those venues, and can only add events for that venue.
We have tried using a number of membership-related plugins that handle custom user roles, but they are too general and focus on access to all of a CPT, not a single CPT.
We plan on having 3 types of accounts.
- Venue Manager (can maintain their venue listing, and can add 2 events or special offers per month)
- Premium Venue Manager (can maintain their venue listing, but can add as many events or special offers as they want)
- Disc Jockey (can maintain their DJ profile pages, similar structure to the Venue and Event CPT)

Finally, this needs to be a front-end editing process. So, we don't want the User to access the Admin Dashboard.
We have purchased a license for WP User Frontend Pro, but have found it difficult to use. See here: http://wedevs.com/plugin/wp-user-frontend-pro/

We are planning to launch this directory in November, but need to have it at the beta stage by mid-October. Therefore, in order for the project plan to remain intact, we will need this done before the end of September.

To summarise:
- Create 3 user role types
- Implement a system that lets us assign a Venue (or Venues) to a user account when the user account is created by us, and allow that user account to create Events for their assigned Venues.
- Deadline is 30th September at the latest


If you have any questions, feel free to ask me on the clarification board as usual.
