Will you work with us?

Hi,
I`m Georgi and am currently looking for opportunities to run banner adverts and to sponsor articles for a few gift-related and other niche sites.
Do you have such options on newslettercollector.com and how much do they cost?
The requirement is to have a dofollow link. And if it's an article - to be permanent and without a sponsored tag.

P.S - If you have other websites as well I'd like to see them too.

Thank you in advance!
Best Regards,
Georgi
