Google Translate is not as much as reliable for English to Chinese translation.

You're right, but I was suggesting using it for Chinese to English, not English to Chinese.

For product descriptions written in Chinese (especially long ones), an automated English translation can be good enough for the reader to make a purchase decision.

Yeah, seems you have experience to deal with that. However, big sellers tend to use photos instead of text description

well, i'd love to help. But the shipping isn't that cheap for oversea customer. Drop me a line if needed.

I'd definitely be interested in talking further, tweet me @chriscbourke - I've been toying with a few ideas for a curated marketplace for international orders, i'll run them by you if you're interested!
