There are already university "fairs" being done here by prominent US (and UK and other western countries) universities. They don't charge anything - in fact they pay to come to Qatar and the GCC. And these institutions provide similar services to yours as to the tertiary institutions here in Qatar.

All of the tertiary institutions here have liaisons with Western universities (again, free of cost to students), the Qatari government also provides similar services, free of cost.

Don't think there's much of a paying market here unless you are looking for students who 90% of the time would not be successful in a Western educational setting - those mentioned above usually screen and advise for students who have a reasonable chance of success.
