I suggest you thought agent to hire the appointed Bun Bun. The agent fee less than HKD 2000 at your side, and the Bun Bun will pay some fee also.
The agent will help you to contact the Bun Bun and arrange all documentation and handling. Included collect the Bun Bun from Airport, body check-up (at phili) and local body check-up (you have to pay).
Also the agent will follow up the visa and keep you inform the status.
OF COURSE ! if you do not satisfy to the Bun Bun, you are free to change another one !!!!
you can contact any agent. This is called Direct Hiring. Normally, it should be around hK$2000 at your side. Your maid should be around HK$2500 =xx petso. If you really like the one you like, you may consider to pay the HK$2500 advance and deduct from your maid when she arrives.
Last Time my bun bun have it done in a HK agent cost $3200~$3,3xx total paid by employer. (I hired the sister of a local bun bun who helped us to arrange it in a local agent in Sheung Wan) We agreed to share the fee on 50/50 basis. This is the cheapest package thro' agent but we had to fetch the maid from HK airport and took her to the agent to get the contract copies on the day she arrived.
They do all the documentation and medical check in Phillippines. The medical check was quite serious as they once hold my application up for a 'mark' found on the back of the maid. They said it was not infectious but need my confirmation to hire despite the mark they found.
