All visa companies do are help facilitate getting a visa - for a hefty charge. I once paid 7,500RMB (1,200USD) for a F-Visa (business, multiple entry) from within China. That's through an agency. Screw the agencies. Go to a consulate and do it the right way without letting agencies screw up your immigration history. They used some business of their inside 'guangxi' (connections) to obtain me this business visa - then when i wanted to renew or extend - Boom! They rejected it. Screw the agencies.
All you need in apply formally with all paperwork, criminal background check (www.chinavalid.com), passports, residence cards, and just skip the stupid agencies.
DO IT RIGHT. DO IT SMART!!
