Require 7 x 500 words seo optimised Product Review Articles

Hi, i need 7 x 500 word Product review articles written by a native (UK/US) English writer.

My budget is £42 (£6 each max) for all the articles. Some can be re written content but needs to be structured with a 250 word review of the product followed by a 250 word personalised review explaining how the product helped you cure a problem but also mentioning one or two minor disadvantages.

This needs to be professional and personal at the same time with the keywords between 1-2% of the total articles. I will provide websites (with good existing content to rewrite) of the products.

Thanks.
