Technical Web Services can manage affiliate marketing on behalf of a customer as well as adsense campaigns.
We are currently working with Affliate Future but can work with a range of other programs as required.
Affiliate programs need a little more attention than regular adsense but can be more rewarding, TWS can help you approach this market.
Please note that TWS are not affiliate 'gurus' and treat affiliate marketing as an optional sideline, especially if all you want are nice colour graphics on your site to give it some flair.
