website customisation for bikeyed.com

I need multiple changes made to the backend of my website to enable semi-automatic functions for users logging into my website. Initial changes to the purchased script have been made but the website is still not at a standard ready for commercial use. The website has been installed with ioncube loaders and decryption will be required. Full access to the site and my host will be made available. I need business users to be able to create their own account and an automatic email confirmation process setup. I need my current backend being split without losing functionality to the website. I want business users to be able to login and post their own deals. I want to then be able to just approve each deal before it goes live. Currently the backend is set up so I have to set up everyones account and add all the deals. This is too time consuming and not user friendly. I need the backend control panel split so business users see a different backend control panel with limited content. I need to setup an automatic payment split 10% commission payed to myself with the remainder to the business user setting the deal with each sale. In addition to the backend I need the flowing things changing to the frontend A few items deactivating on the front end the initial Pop up (select a city) removing Images adding to the subscribe box Text areas adding (which can be changed in the backend of the site) Ability to change the (featured on) image in the backend control panel Facebook and twitter icons at the bottom of the page linking to my Fb /Twitter pages I realise this is a tricky job and can not be completed in a few hours but their is a limited budget so freelancers with a reasonable started milestone will be considered.
