Site like spareroom.co.uk in wordpress

Hi there, My name is Charlie. I have a vision of easing a housing crisis in my local community and need some help building a website to do so. We need the design and development of a site like spareroom.com. - Already have domain and host using Wordpress. - Should be developed with buddypress. - Should be built with plugins in order to make maintenance easy. - Feedback(reputation) system between landlord-tenant. - SEO optimized/google analytics. - Developed according wordpress best practices (Custom posts, child themes, plugins, etc). - Free and paid listings (Upgraded users can: Early Bird Access - (contact Free and Bold Ads less than 7 days old); Place a Bold Ad - (stay higher in the listings and double your enquiries). - Must have a search function using maps. Looking forward to seeing who may be able to assist with this. Kind regards, Charles
