Wordpress Real Estate Membership Site

Looking to hire a wordpress / php developer to finish off a site that is in progress. The base of the site is complete (post property listings, search for listing etc), however many things remain to be completed , such as having listings expire after a certain amount of time, email notification on expiring, saved searches to member profiles , some more work on google maps integration in the site. Plus finish off the permissions based on user role / purchased access level. As well as set up the transactions through Pay Pal, either using Foxycart or perhaps a plugin for wordpress. I'm the graphic designer of the project, so would be handling all the skinning of templates, I'm just looking for someone to help finish off the functionality and to help get this project launched for the client.
