Hi,
I've got rich experience about submitting Android app in Chinese app stores.
First of all, your link about the Chinese app stores is out of date. Actually you don't need to upload to all 10 stores to cover Chinese android users. I'd like to share you more insight about the market.
It's not a quick job even for native Chinese android developers. Each stores have their own process of accounts approval and application approval. It will cost you 3 days to 2 weeks to get your app online.
I finished multiple jobs about uploading into these Android stores. I'm familiar with the process and the requirements of each stores. I made a table of detailed information about all these stores. No one else can give you a better offer.
My proposal is to upload into the largest 4 of them and see the results. If you need new account created for you I'll collect some information from you to complete the process. We can talk about more details via PM. If you don't want to use your own information I can help publishing with my accounts which are active for all these stores.
Please contact me. Looking forward to your reply.
