For adwords, better build your own design website and capture their email with some plr graphics pack targeted to new business owner/new websites (if that's your target market). Expect cpa around $5 per email if not more. Once they signed up, email them about how important it is to have a great business logo, etc, etc. Give them info about your $300-$3000 logo design service with satisfaction guarantee and unlimited update. Send them your design samples and testimonials. At the end of the day, they are your own customers, you can do pretty much anything with the list, upsell white label web design/hosting/seo/etc, downsell whatever. For non buyers in your list, you can always send them to your fiverr gig with your affiliate link.
Not sure how to do this? Find some great design blog (9 9 designs blog for example) and sign up to their list. Steal their email idea and make them your own.
