Hello katze1 - doing both I suspect will double your chances. There's quite a few banking jobs in Doha, due to the boom in financial services. One bank to look at is Al Khaliji - a new startup bank which is making waves in the usual 'stuffy' world of banking. They have a careers page where you can apply directly to them (www.alkhalij.com); other banks will have something similar if you go to ther websites.

In terms of recruitment websites, some of the top ones are www.reeds.co.uk, www.bayt.com & www.gulftalent.com and www.gulfjobsites.com/jobs/Qatar will give you most of the other sites.

Let me know how you get on/or if you need anymore help - good luck.
