Can anyone help with how I'm supposed to get a visa?!

I'm coming from the UK, my boyfriend is being relocated for at least a year in September and marriage (although expected one day) is a bit of an extreme and rushed way to get me out to Singapore with him.
I am therefore not elligible for a dependants pass, and have no A-levels or Degree.
Is it easy to find a job while still in the UK? Is it worth coming over on a holiday visa to look?
Does anyone know how succesful TEFL is if you want to teach English?
HELP!!
