Since you're slow right now, try designing a flyer showing what your business is all about. Stuff some envelopes with a cover letter, the flyer, and your business cards. Sent these out to the businesses in your area. Make sure you include something about having time to meet with the people you're sending the letters to.
A couple of years ago at our "slow time" we designed the flyers making them tri-fold and two sided. Got a printing company to print and fold them for pennies. I think it was about a 4000 count. We put one in every invoice that's sent out whether it's a new customer or steady Freddy. We also got the phone book out and started sending these out as cold calls.
Only you can be the expert as to what people want in your particular area. You live there and if you're keeping your eyes and ears open, you'll know what it should take to grow your business. Most small businesses just don't know how to make them grow.
This has worked for us. We also do trophies, plaques and shirts along with signage, so if someone comes in looking for awards, they can see we do more. Hope this helps.
