Pre-Relocation to Bangkok

Hi everyone!

My partner has been offered a job with a Thai National company for a period of 5 years. We will be relocating there from Australia in the next few months. I myself would like to work there as well if possible. I am an Executive Assistant and have noticed that many similar positions in Bangkok prefer you to be Thai bilingual. We also have a nine year old daughter requiring International schooling. If anybody could help me with any of the following I would be most grateful! My questions are:

1) Best international schools?
2) What part of Sukhumvit is best for apartment/condo living?
3) Recruitment companies for expats?
4) Visa info for partners
5) Nanny/ babysitter info on agencies or possible contacts?

Thanks very much everyone!
