Special services for Indian freelancers (Translate English Documents to Hindi) Pages consist in 50 pages

My project is for a special type of services for Indian freelancers. I'm in need of someone to translate company handouts and brochures from English to Hindi. The expected turnaround time for each document is 72 to 96 hours. Therefore, I need someone who is proficient in both Hindi and English, and able to work quickly and accurately. An understanding of technical language is preferred. If the project is completed satisfactorily, I am open to extending this project and establishing a longer-term relationship with the successful freelancer.
