Changes needed to existing database website

Changes needed to merryhillautocentre (dot) co (dot) uk Stock page: i need different page counters rather than dropdown list i need Page 1 2 3 4 5 6 7 so that they are links and can navigate to that page immediately by selecting that page number, and as more cars are added this would increase. Also on Stock page i need it to display the Total number of cars in stock. Car Listing page: Need the main image above the thumbnails to be of a bigger and grand size than is, so when user clicks on thumbnail it becomes bigger image. Also on Car listing page: User on database when adding car must have options to add a link to Ebay listing and a link to [login to view URL] listing and link to AutoTrader listing of that same car which will then be displayed on car listing page as See car on Auto Trader for example which will be a link that was provided in the database for that car listing. Need it done asap just small changes.... database is mysql and site is php
