Part-time Thai Personal Assistant in Pattaya

I am looking to hire a personal assistant in Pattaya, Thailand. You will need to assist me with tasks such as organizing travel / dinners, event scheduling and management, and Shopping & Errands. The position may require in-person (offline work) - e.g. visiting a restaurant to choose a table etc.

There will be a practice assignment (paid) before regular engagement. 

Thai language is a requirement. This is a part time position at $15 hourly. I spend up tp 4 months in Pattaya a year and this can be a long term engagement.
