Urgent: edit 25 x 250-300 word seo product descriptions to produce + 50 x 250 words

I have 25 x 250-300 word product descriptions, based around popular car brands. I would like this copy editing to produce 50 x 250-300 word versions which are location-specific and unique.

Original copy is location specific, this copy will be supplied along with the locations for the two further descriptions and the main key phrase for each piece.

I need this completing by Sunday 16th December, at the latest. So please only submit a proposal if you're able to meet this deadline.
