Have used i2visa several times over the last few years to fast-track and simplify the visa process for China as well as process the endless documents required. Not only is the service super fast and effective, but Joey Zhou has always been happy to offer huge amounts of help over email and phone for any (of the many) questions that I had about the process. i2visa stays on top of and ahead of the ever changing rules of the Chinese visa system and because the internet is currently littered with out-dated and false information about Chinese Visas (Especially Z) it is well worth the money for taking the whole process and putting it in professional hands.
