Any good visa agents for helpers in BKK? (Bangkok)

I am trying to get my Filipino nanny to come and live with us in Bangkok. She has been with my kids for 2 years and they are understandably unhappy and unsettled in the new country. Is there any agencies who can help with the visa/work permits that anyone can recommend. I don't want to bring her on tourist visa and get into visa runs and was looking for more permanent solutions. Would be grateful for any recommendations. Thanks in advance.
