Build a photography portfolio blog/website for photographers from my locality.

The idea of this website is to create a unified portfolio for the photographers of my locality where, they put up and present their art and work. The website should look like a professional gallery with a photographic look and amazing design. I want it to stand out of the crowd and attract media and professional attention. I have done the major work of buying a domain, hosting it and installing latest version of WordPress. I just need professional expertise in choosing a perfect theme, best and suitable plugins and crafting out a website that is up to the idea and is perfect and professional. The website should have the following features: 1. Amazing homepage with gallery of photographs, featured slide shows and random slide show. 2. Separate logins and profiles for each photographer, and also for non photographers (normal users). 3. Uploading feature for photographers on their profile/page directly but only after getting a approval from me. (So that only professional photographers can update their work not the naive ones). 4. Separate pages for each photographer with slide shows and gallery, follow button for the viewers and option to hire or buy the work of photographer. Also, list of each photographer's page in the main menu. 5. Facebook page feed, twitter feed, social discussion (comment box), social login, social sharing, social chat, Instagram sharing and feed, Fb and twitter like button etc. 5. Views counter on each gallery and photograph and also on the page of each photographer and also ability to like them. 6. Classification of photography in different types, like travel, portrait, child, nature etc. 7. Discussion forum or group for the photographers and users. 8. Chat feature for registered members. 9. Photographer ranking feature from the users. 10. One page gallery where all the photographs on the website can be viewed together. 11. eCommerce setup for staring a shop for selling designs, arts and photographs from our website. 12. Wallpaper downloading setup. 13. Blocking features to block spammers and other fake users 14. SEO optimization to get search engine rankings. 15. Responsiveness and speed. [login to view URL] and other portfolio websites where photographers present their work to the world is an inspiration and example for this idea although my idea is on a much lower scale. My website is just for a locality. Thanks
