If you wish to have perfect language in conjunction with technical content, my editing services will provide your exact needs. Bid is based on up to 50 A4 pages, but can be negotiated. My recent success includes editing an economics thesis with plenty of technical content, for a Chinese student. My business is full time and home-based - thus I can devote sufficient time and energy, as well as be available for re-reviews, to give you the confidence to select my bid. Regards, Ray.
