I run a few different businesses. One of them is a local web design and development agency. We're usually never stuck for clients, but we encountered a slight drought in early December. I decided to implement an idea I'd stored up for such an occasion. The idea not only worked, we're booked solid for 3 months.
What I did: I opened up all of the local buy & sell Facebook groups in the area and posted a brief ad with a picture, offering an instant PayPal payment of £10 to anyone who referred to us a new web design client. This was on a Saturday morning. Come Monday morning: over 3 months' worth of work.
Give it a try yourself. Can't hurt, right? I offered £10, but I see no reason why $10 wouldn't do the trick. You never see this kind of offer (at least not in my own local groups) and £10 to some people is nothing to be sniffed at; especially when they have an uncle who's been talking of getting a website, or a brother who needs one for his used car lot. You get the picture.
I'm off to watch a movie!
