Honey, the reason a freelance visa is so expensive is that it is illegal. It is a way to sell yourself into slavery. Yes, there are unscrupulous people who will offer you a visa and extort money from you every month. They will threaten you and exploit you and you will have NO recourse! They can make you work, or worse, and report you to the police for deportation if you do not comply. I am SO sorry your husband doesn't make enough to sponsor you and your precious baby. The only solution I can see is for you to get a job here in Doha. Good luck.
