Edit and upload pages to website

I run a low cost ebook and software website. At the moment it has about 100 products but I have a further 300 to add to the site. The work involves some simple editing the the individual salespages (provided) and adding payment buttons (html provided). In addition I have organised the site into broad subject areas and have a sitemap for each subject. It will be necessary to add a linked image (provided) plus a short text entry (10-20 words) and a further link to the appropriate salespage. I will provide copies of the existing sitemaps plus a number of new sitemaps for new topics. I have resell writes for all ebooks and software and will provide all the pages and links in a seperate folder for each product. On completion the folders will, in their entirety, be uploaded by me to my site. The name I give each folder will become the directory name on site and the links in the sitemaps should reflect that directory name. All links are to be checked. Please quote a single total cost for the complete job. I am looking to have the job completed as soon as possible - preferably by the 24th August.
