Are there any companies anyone out there recommends to create creatives such as Banners and LP's?
Thanks!
Bannerslanders.com
There's quite a few, though Attila recently invented this service specifically for affiliates.
There are others that specialise more in landers than banners, e.g. landing page guys, urr forumdesignerX, gah I forget. Browse through the buy/sell forum and you'll find a few!
