G'day Marty, Craig, Neil & Doug, here we can have a pop up with a notice about any sorts of specials you are doing, any promotions you want to make people aware of etc.
We could even just have a photo of yourself and the team in action, with a brief message saying something like "Hi, this is me and my team. Just a friendly heads up to be careful about who you select to provide these kind of services. There are plenty of 'dodgey' companies out there."
Again, this is just an example. We don't have to have a pop-up at all. Just want you to be aware that this sort of thing is possible.
