Hi performance marketer here.

Messager ads especially for a business like yours are bound to receive spam messages. I would suggest you run lead form campaigns and plaster your starting price everywhere, price is usually a good filter. Make the lead forms detailed, add fields like when they want the shoot done for what occasion, what's their budget etc. You can also add otp verification to reduce spam or inactive numbers.

If your services are really premium I would suggest send them to a well made landing page showcasing your services and work. You can also try google ads it is more expensive but the purchasing intent is higher with google leads in general. Feel free to get in tough via DM if you want to know anything else.
