Great questions, Maxime! The good news is that your service will sell itself once people see it in action, so build your strategy around proof.
A few things worth exploring: Do you have a newsletter or email list with your existing customer base? They already trust you, and a simple "did you know we also do this?" can go a long way. Are you capturing before and after photos on every job? That's your most powerful marketing asset for this. And is the service offering clearly visible on your website?
Local Facebook groups can also be a great low-cost way to test interest.
Where are most of your leads coming from right now? That might help point to where to focus first.
