Complete a website project

I have a site that is finished to 80-90% the design etc is alreday made. The background is (admin, payment etc) is OSCommerce. So I need a great OSCommerce programer. And I programer that can make a designertool, similiar to t-shirt (design your customized t-shirt), ajax!!!! What is needed to be made. 1: The site is in serveral languages, and it is not perfect, so this has to be looked over( imean that the language must be perfect, I do not have time to check over everything). I would like to have a language support so if a swede enter the site the person should be entering the site in swedish. 2: The resolution of the site is not 100%, it looks different on different comupters (depnding on the monitor size) 3: There are serveral fonts on the different pages, shouldnot be that. so that need to be fixed 4: Promo code in checkout installed, shoube be made so so I can choose to I one that works for serveral people and a code that is jujst possible to use once. Observe: the desingertool is on the site today, but it do not work correctly, just loading 3: I have a designer tool (ajax) that do not work,I had malware issues on the site before, and it not not work. The designertool is made like a designer t-shirt designer. You choose the shape (i my case four different , oval, round, etc), the you uplaod your pic, add filter to the pic (can crop them etc), ( or just color the shape) , then add some text on the shape. This designer tool has a error in it now, and do not work. And it needs to be fast, uploading pictures, and addding filters needs to run fast. 3: Currency, should be updated daily, when you choose BUY NOW in my desingertool, you should be able to choose currencys (five different) and thease should preferably be automaticly updated daily. 3: Calculation algorithm, since this site is about textile, you shoule easily be able to change the parameters for the pricing. It is now calculated with widht and length. m2 4: Close integration with facebook, I would like to have facebook made (cororate site made). 4:1: So if you for example share your buy you have made on the site, on your personal facebboksite, you will get a discount in the sites checkout page. 5: Payment integration with paypal, 2checkout and Klarna. 6: The newsletter needs som attention. 7: A form is made on the site were you upload pictures, this do not work to 100%. 7: Searcheninge visability, make my site visual!!! 8: Add additional minor fixes (that can accur and that I see you as a freelancer will be ok to fix, if it is not major work. I will send the adress to the site (for further investigation) to the GAF that I feel can make this job promt and great. Since I have hadfreelancers that has drop out of the projct earlier. I will not pay anthing upfront, I will only release when I see that the work above has been made.
