Customize Wordpress Event Website

Hello, I am developing an event and directory project using Templatic's Tevolution/Directory Theme/Child Theme. There are several options I wanted to have that aren't part of the base theme and was wondering if you would quote the costs out to accomplish. Site is in Staging right now [login to view URL] (Site PW "SoClassi") 1) Default Organization Information for a User. I envision Users are Theater Groups and Theater Directors posting Audition/Show information. As such there will be multiple submissions. There are a couple of ways to accomplish this. Once they post their Theater, Allow for that Theater and/or Theater Group in the Directory to be associated with an Event. OR In a users profile have the default information be pulled from there. (Ie. Organization Name and details.) The former is definitely more relational and cohesive. 2) Add a comprehensive filter to find events by date, category location etc. 3) Add a map view of Theaters & Instructions (Post types with custom fields) Request that any/all of this functionality be done without interfering with the theme or plugins part of the theme so future updates can happen without affecting these code changes. Thanks, Peter
