Travel agent in Shanghai recommendation

Hello all, can anyone of you recommend a reliable travel agent who could help me to arrange a one week holiday trip for me and my 1,5 years old daughter? We would like to fly from Shanghai to some sea side (Sanya, Taiwan or Philippines or Malaysia)We do not need expensive holidays, my daughter just need proper sea and beach and place to sleep at. We would like to leave August 15th. We are budget limited. Thank you. Zuzana
