I guess different packages depends on what's in them. I've been using 3 packages that mostly differ by how many speakers and how many hours. I've been advertising club lighting (which is just adding 2 scanners and 2 color changers or mirror ball) as an add on and only had one client that wanted the extra lights in the last 3 years. I've also had prospects that thought I was pulling a fast one by suggesting they need more speakers for an extra $100. So those packages haven't been doing too well. I've also had weddings in venues that I didn't know the layout of, and had to add more speakers anyway once I got there.
What I've been doing is raising my price a little each year, but offering a discount that's still yields a higher profit than last year's price. But I like that limited time offer idea Rick. That should motivate prospects to sign up quicker. Everyone likes to feel they're saving money IMO.
