Need a Ajax,PHP Coder (replace Banner with video)

You need to know where files are at in FTP.. ..Don't tamper with other files as i see whats going on in my C/panel etc....Don't create special FTP logins.....0-10 feedback bidders will NOT be Hired by me....Do Not screw up any of my other functions already working as there are no errors....Other then the templates i will remove,,regardless message me if you can do project..Will do 1-milestone of $70.00 MAX and released after a functional completed project,dont request milestone wihout me & you [login to view URL] is for 1-day bid or DO-NOT Bid & over Bidders will be Deleted..Agreement is:Project will be closed when 24 hours end.... (1.) Replace BANNER section of Video Page with the same form of YOUTUBE video/view Big image section that i currently have in my Comments page..Currently that Big video/image switches all videos and images instantly upon pressing the prev and next buttons to any side...Need this same version type added to the LOGO section in Video page but to switch Videos only from video page..Use same/similar codes on the CSS currently seen big image which contains the buttons,height ,width,color,background,margins,etc..You will use 1230 pixels width by 525 pixels in height to replace logo section for the New video display..(See screenshot I did for sample only)...........(2.)Use the same AJAX file/s which are used (for the call from file)...The place comment button should be added in the middle of the next and prev buttons ans as soon its pressed it should direct User to place a comment for that SPECIFIC video,,if I open comments it has to show comments for that video as THAT IS WHAT IT DOES ALREADY SO YOU SHOULD KEEP IT THAT WAY....If you create another file is fine but you will need to contact me so I can name it as that is how I find my files...(3.)The new Big Video you will add to the replaced LOGO section should always display the last video or newest video that was uploaded to video page when any User enters that video page................... NOTE: Most of the codes (youtube,CSS,& Ajax codes) needed are there and should help.. Reminder: For the 3 buttons (see screenshot Red circle) must add and have them functional and added as seen..You will need to keep my Original Logo BORDER that has red arrows pointing in screenshot...
