Vorrei sapere in quali giornali si possono pubblicare, in Italia,
Spagna, Portogallo e possibilmente anche Stati Uniti, degli annunci
gratuiti o a prezzi convenienti? Inoltre quali sono i siti internet
pił conosciuti ed efficienti in cui si possono pubblicare annunci
gratuiti o pagando anche una piccola cifra, inserendo possibilmente
anche dei link?
Grazie!

in English:
- I am looking for newspapers/online-magazines where I could place an ad
in the field of jobs/education in ITALY/Spain, USA and possibly Portugal - 
it should be
a) either a print medium where I reach lots of people and can put a
www-address url (i.g. www.site.com) into the ad without the need of a
telephone number AND reach LOTS of people
b) or/and an internet site (like gumtree.com or vivastreet.co.uk)
where I can put an ad for free or pay an AFFORDABLE fee up to
~20$/month.
c) a website of a print magazine/newspaper with the same conditions
but the ads being published on print AND internet.

Thank you.
