Clean up of HTML descriptions of products for website

Hi, I have attached an excel file which consists of the description as they appear on our website. As you will see some descriptions look nice but some look horrible. I need someone to clean up these descriptions, and provide them back to me in in clean html code on the excel file. You must not reorder this file or re-arrange this, as we will then add some other information and upload to the site. These descriptions have been given by some of our suppliers, and some had tables, that are not showing, some are perfect, some are just not readable. So i need the new description to have h1 tags, tables where needed, properly showing in our site. The new descriptions will be presentable, with headings, with paragraphs and generally correct html structure. Not all products need updating, out of the 2500, i would say about 500 need fixing, possibly alot less. I will provide you the website so you can see how they are showing right now and then you can fix directly onto the excel file. Payment terms: once the winner of the bid has been decided i will put as a milestone the amount in full. once i upload the modified descriptions onto the site and all is done well you will get the funds released. Duration: No more than 1 week please to complete the project.
