The fastest way to do if you already have a work visa for her is to book her as tourist to Thailand. Two way ticket & 2 nights stay at the Bangkok Hotel would not cost you over 400 USD.

Once she is in Bangkok she can board a plane to Qatar showing her work visa and a one way ticket to Qatar.

There is so much red tape in the Philippines that I could take over one (1) months to process the papers.

Surely she will believe in you.
