Agriya's GrouponPro. small customization needed

Site is [login to view URL] it is a groupon clone built by Agriya. the project: Part 1: In the users member area ([login to view URL]) is a link to "add a deal" see attached screenshot. [login to view URL] What we want is for you to hide this "add a deal" link from this area. Don’t delete anything as we are still using the 'add a deal" feature, but we are not leting the "users" have access it. Part 1.5: Also In the users member area is a link to "clone deal" (you have to hover over existing deal) see screenshot, [login to view URL] What we want is for you to hide this "hide clone" link from this area. Don’t delete anything as we are still using the feature, but we are not leting the "users" access it. Part 2: we need you to create a simple log in system (see mock up attached [login to view URL]) this will allow my clients staff (salespeople) to access the "add a deal" area and add deals. please link this login to the "adda deal" page [login to view URL] Part 3: In the business sign up page: [login to view URL] we need an extra field for ‘Sales Person’ at the top above Username. Attached screenshot [login to view URL] Part 4; after the salesperson has logged into add a deal area and "added a new deal" this deal will show up in the master admin (IMPORTANT: this already works..nothing to build) BUT I need the salespersons user name to be added to the deal in the admin (see attached [login to view URL])
