Which Plugin does WPMU use for Custom (to find developers or to find a project)?


I am looking for the right plugin for my website similiar to what WPMU has one (Custom) to find developers or to find a project.

My website will be more about homeowners and contractors.

For homeowners:

To request a service (by category) to do the house project like installing a programmable thermostats. Ask for “quote” from contractors,

For contractors:

To browse projects (by category) and bid the project.

Also I want contractors to provide business address, phone, email and business phone number.

Your help is greatly appreciated and definitely will save my time to hunt down for the right plugin!
