This goes into smaller details:

1. Your potential employer has a good reputed but it is a family owned business.
2. Good companies generally tend to look for qualified accountants in senior accounting roles and they are willing to pay more.
3. MBA is not a relevant qualification for any senior accounting position though you might have your degree complemented by relevant experience. Again with MBA, it does matter a lot 'MBA from where'.. I mean which school.
4. Since you are not a qualified accountant, they might not be willing to give you a very good offer. QR 10k to15k (excluding housing) would be generous if you could negotiate that with them.
