The problem, as previously mentioned, is that current, well established customer may catch wind and get soured or worse, demand the same!
Sounds like an endless domino effect. I would focus on your marketing strategy on different levels.
- Targeting locations (demographic/logistic targeting)
- Media (identify appropriate sources, print, phone book, local paper?) ps...I THINK THESE ALL BLOW!!!!!!
- Product Enhancement (better logo, tagline, graphics, different message vehicles, etc..)
- Reduction of Past Expenditures (you've had a winner in ROI, now how do you reduce your price?)
Aside from marketing, can you identify inefficiencies in your service delivery for 2013? If so, what do you need to adjust, buy, stop doing, start doing, etc??? Increasing your margins is a multifaceted endevour.
Dig deep, now's the time its freakin cold!!!!!!!
