Hello,
Check out Clare Cullen's website. She's a doula in Doha, from the UK:

I'm due in February as well :) and have done a course with Clare, she's great. She also has contact details for other doulas in Doha. One other name I know of is Angela Upward. I've got her phone number let me know if you'd like it.
Congratulations btw :)
