Magento Store Customisations

Hi Freelancers, I need 3 tasks done to a Magento online store, so I am looking for a skilled Magento developed to get them completed for me in the next 5-7 days. Here they are: 1) Check-out Timer Every item on this online store is a one off, so there will only ever be the 1 item in inventory meaning it will sell out very fast. We need a function that makes the first person to click 'Add to Cart' the exclusive ability to hold the item for 5 mins.. A pop-up / notification needs to inform the customer that they have 5 mins.. A countdown timer pop-up would also be great. *I will provide psd files for this pop-up and timer (if you can do it). Please ask any questions with this part of the project because it is VERY important and needs to be 100% functional. 2) V.I.P. access for a testing period The site will require a 'Coming Soon' landing page while testing in being done (already coded and ready). During this time VIP customers will be given user logins and password to access the online store and make purchases before being open to the public. We need the Landing Page to have a special login for these VIP users. These VIP users will only be able to see the front-end of the site. 3) Two Departments / Splitting Profit and Orders Two different people work for this company, 1 female and 1 male. They each individually manage the MENS and FEMALES products on the store.. For this reason orders, invoices, and other details need to be accessed individually. This means two seperate logins. When a product is uploaded there needs to be a way of putting it into a men’s category or a women’s category. So that when they need to process orders they only have to process their own MENS or WOMENS products. Very important that they are able to seperate the men’s and women’s profit on screen. Please note: all orders are still going to go through the one bank account/paypal, they just need to be able to split up things to help separate shipping, etc. I'm happy for people to use/modify plugins to achieve each of these tasks. If you have ideas on how you are going to finish the jobs then message me to get my approval! Only bid if you are ready to start work straight away and finish before Wednesday next week. *** Do not message me a list of all the Magneto sites you have done, I need specific details on plugins and customisations ***
