hello,if you will get thru an agency be careful of one thing most agencies will tell you you can refund your money or change the helper within 3 months in case you did not like her performance but once you are there many will try to escape this and gain time so that they will not change her,also many agencies will teach the helper that be good at least in the trial period then you do what you want after the trial period many of them starts behaving bad and then what can you do you are tolerating because you do not want to loose the huge amount the you paid the agency and the helper knows all these details,better if it is acceptable to you get a locally hired stay out helper under her own sponsorship you can post an add for this
