And this job description for a flyer distributor in English:

http://myjobsearch.com/careers/flyer-distributor.html

A flyer distributor hands out flyers to promote events, venues or establishments. The job is referred to as "flyering" in the trade.

A flyer distributor is usually employed by an establishment or event promotion company to market an event or establishment through handing out flyers to the public. Flyer distributors can be assigned to post flyers through front doors or to hand out leaflets at a given station, usually outside the institution building or a potential ‘hotspot’ for customers, for example outside a student union to promote nightclub events.

(maybe a more elegant term exists)
