Dear Naser,
Posting a CV is not so difficult. Since you already have a gmail account, all you need to do is go to compose mail, fill the To: with the recipient's e-mail id , fill the subject: 'My CV' and click attach a file to select your CV from the Computer. Ofcourse you need first a CV in microsoft word format.
You can search for vacancies in Gulf times classifieds.
Best wishes.
rejoice.
