Let us pay YOU for your land! DKOI Digital Signs is located in Rock Valley, Iowa and we are always on the lookout for new locations in high traffic areas to set up our digital billboards. We would like to talk to you about making a deal where DKOI pays you to install our sign on your lot. We own the sign itself and take care of everything: installation, maintenance, and operation of the sign on your lot. We handle ad sales and content control from our office. Got questions? Reach out to us at 888-995-DKOI (3564). Interested in making a deal, please fill out the form.
