Salam Salma
One bit of advice is make sure your nanny, housemaid is aware of what the job entails cos the Sri Lankan maids are an ungrateful lot and by and large not genuine.
A pal of mine lost a lot of money - after the visa was stamped and paid for, the maid disappeared from their house and ended up at the SL Embassy and wanted to be repatriated.
So be careful before you lose your money.
Cheers
