How good Is this offer ???

Hi. I recently revieved following jib offer from a clinic in al ain -- 12200 aed + 20% commission on income above 40000 aed/ pm. For example if the clinic earns 50000 aed pm then i get 12200 + 2000 aed = 14200 aed salary. The clinic provides only medical insurance and visa. No accomdation and no transport allowances provided. Which means i will have to arrange for it .AND  I AM SINGLE WITH SIMPLE LIFESTYLE.
PLEASE ADVICE WHETHER I WILL BE ABLE TO SURVIVE AND SAVE MONEY OR NOT ?

where r u working..?

This offer is from a private clinic in al ayn , abudhabi.
