If it was me, simply scrape images related to the fiverr gig then create boards / group boards in the topic and begin adding your fiverr gig URL into the source URL's of some of the pins. Clicks would be easy, conversions harder but would all stem from the pin as there is no way to butter them up before the fiverr gig landing page.
Not sure what you offer in your gig, but lets say this was design work like "Tattoo Designs" and you sell people jpg's to take to the tattoo parlour.
You would just scrape a big folder of tattoo designs "sleeve tattoos" "back tattoos" "music tattoos" ect ect, clean up the folders removing any poor images or risque stuff. Create boards for each of the different types of tattoo design and start pinning them with your owl URL as the source on about 45 - 65% of the pins. People searching designs are likely looking for inspiration or the "Perfect tattoo" so a service that offers design work based on what someone wants goes hand in hand.
If you can offer up some more info on the type of service you provide would help folks help you.
