Commercial-technical document English review (10p.)

I need proof checking (grammar, spelling) of my commercial offer in English. The document has 15 pages long but less than 10 pages of text.

I look EXCLUSIVELY for people having:
- English mother tongue
- experience with commercial document
- can do the work for Thursday afternoon (CET time) at the latest

Please don't waste your and my time if you don't fit these criteria.
