Expressions of interests and quotes only: Build a multivendor marketplace website

INSTUCTIONS: PLEASE NOTE THIS IS AN EXPRESSIONS OF INTEREST AND QUOTE REQUEST ONLY (Not a real project) AND THE BUDGET IS NOT REAL, please bid/quote for the job according to your rates, either hourly or fixed price. I would like to find out the approximate cost and time needed for such a job to be done, before I post a real project. PLEASE ONLY APPLY IF YOU ARE A NATIVE ENGLISH SPEAKER, YOUR BID WILL BE IGNORED IF YOU ARE NOT (I need the back end and the front end in perfect native English). PLEASE THE WHOLE THING. For new bidders: To make sure you have read the whole thing and to screen out non-native English speakers, please mention the secret word found somewhere in this description, in your bid. I would like a multivendor marketplace website built with the following features: - Website is for digital download products only (pictures, videos, audio, photoshop brushes/actions, 3D models, scripts etc). Please note, this is only a desktop website, I do not need it to be converted to mobile format as well, so you don't have to spend time making it too mobile friendly. - I need administration access to manage commissions and approve/delete vendors if needed - Vendors can sign up without approval and use the front end to manage their shop - Pictures, videos, and audio should have a watermark automatically attached when the vendor uploads it. For pictures, it should get automatically converted to a lower resolution with a visual watermark added, videos should also have a visual watermark added automatically, and audio files should be the full file (I find 30 second previews not very useful) or up to 3 minutes, which ever is shorter AND have an audio looping watermark eg a voice over that plays over the entire track that says something like "Sample from Website" - Customers can rate and leave feedback * - Customers can log in to post requests eg for a specific image type, and sellers can browse requests and create products accordingly * For the buying process and feedback process, you can make it so that either: - customers can purchase without needing to make an account and log in, so that they get an encrypted link after paying to access the file, this link would also have to be sent to their email, a separate link generated for them to leave feedback and rate the purchase (the covert word is 'mononucleotide') AND/OR - customers have to make an account and log in to access their purchased items from a central location eg "My purchases" and to leave feedback Would be nice to have both in case some people can't be bothered to sign up. - Benefits for customers who sign up: bulk discounts and points for purchases which can be redeemed for more purchases, buy recurring subscriptions. - Feel free to use existing API or software plugins Possible other features, which I have not yet decided on. As I said, this is not the final project, so please leave a quote according to the current one, and leave any relevant messages according to possible further requests.
