179932 oscommerce repair or reinstall

(remove z)[login to view URL] Low quality programmer has made a mess out of my cart when installing mods and requests. Im looking for someone to fix/replace and bug check. Problems are checkout- doesnt work, click checkout, it keeps showing cart. Wont allow paypal checkout. Requirements I want paypal checkout to post back to cart, showing order. I want paypal,google and moneybookers to allow passing of shipping costs by weight. I want a custom google checkout placement on checkout page. I would like the checkout button and google checkout button to be near each other in a neat fashion. Id like emphasis on the google checkout. I dont like the simple google checkout button strangely placed below the original checkout button , I would like it blended in better. I would like a data feed contribution installed so I can automatically have products fed to google and other such shopping portals. I want to have a faster checkout process, prefer no account required for checkout. I only want name, address, products, then checkout, very simple checkout wanted. I want to keep my site with working function as it has now. Same colors, text, products, buttons, meta tag generator, seo friendly pages, featured products (replaces new products), country selection mod, custom info box, custom payment option box on front page, paypal, google checkout etc. The person I choose will have a long term relation with small jobs and updates every week or so.
