Lithophanes, custom boxes, go down to your local Marina and get to know folks if one is near by. Local sports club to see if they need or know of some one needing plaques. Also any of the local schools or Social organizations. With your current set up signs of any real size are pretty much a no go. Custom wooden mugs sealed with acrylic. Custom parts for local RC clubs. best thing is get out to you local craftsmen and find out what they need in small project items.

Best of luck and hope that these ideas help a bit.
