Anyone hired maid directly on your own without agent or got help from agent to settle paperwork? Would like to know the procedures and costs involved. TIA!

Yes, but easier if transfer rather than bringing in a new helper. You can print off all the paper work you need online, apply for work permit etc. I don't think there are many costs involved, I think applying for work permit was maybe $30... Can't remember. Need insurance etc but I presume through an agency you'd still need to pay for that anyway!
