I want someone to finish and fix my website

I want you to go on the website: [login to view URL] . then check it and see any change that you guys can come with and see what is working and what is not working and how can it be better. a lot of stuff are not working not he website concerning back end and front. I want when i receive my order for it to be very nice and flow well. I want a great chat system for communication to be able to accept unlimited user and flow well. These are some stuff that i acknowledge on the website but of course there is stuff you guys can see that i do not. for front end improvements,: 1) (Search by brand or model number) Add a purpose label 'Look up your product', 2) try to communicate the use of this UI element a little more effectively. 3)drop the size of the product labels, 4)there is too much wrapping on smaller mobile screens (iphone4). 5)clicking accept reloads the page to the top, 6) we should try to keep the reload where the user currently is on the page after clicking. or turn the 'accept' button into a 'continue' button, and ajax the offer. facebook sign in clears my trade in form, lets pass back some redirect params and tell the client to reload where we were when we activated the login button. Checkout has some formatting problems, 7)margins are not right the disclosure triangle on the step description is not right, 8) the text flows behind it on mobile. confirm address refreshes the page to the top (perhaps on invalid form data.. needs better form validation), losing my checkout form scroll position thank you page is off center, needs formatting adjustments. 9)[login to view URL]{{trackingId}} has mobile formatting problems, could use some styling. 10) Tracking order needs a better invalid data redirect, it currently takes us back to the home page with no warnings. for front end improvements, for back end improvements - login repair - chat upgrades- Better chat system that can take unlimited users - tracking shipments - past orders -better way to receive the orders and able to track them very well -Shipping label need to be sent to customer in PDF Mobile website: I want the mobile website to be well done and completed.
