Visiting Beijing in March

Hello,
I will be visiting Beijing, Xian (Terracotta Warriors) and Shanghai from March 26 to April 02. Due to language problem, I was wondering if I can have Bangladeshi brothers residing in those cities could assist me. I am willing to compensate (pay) for their time. I would also like to be picked up from the airport.
Please help me.
Thank you.
Babu
