Wordpress membership website

General information for the website: I am looking into the idea of creating a casting call website similar to: www.mediavolt.co.uk
Kind of development: New website from scratch
Num. of web pages/modules: 20 static pages plus profiles
Description of every page/module: I can go into great depth, however if you look at casting sites (like the one mentioned above). If you can get back to me with a rough cost, site will have pay to view and apply for jobs option, profiles are free.
Description of requirements/features: Happy to accept plugins, but you must be able to customise and hand code.
Extra services needed: Installation, Customization, 3rd party integration, Optimization, Other
Specific technologies required: Wordpress
Similar urls: www.mediavolt.co.uk or www.starnow.co.uk or www.castingnow.co.uk
Extra notes: Fully automatic membership site with some moderation on profiles and jobs.
