Marketing support to bring new clients to Hiking Nation

I run guided hiking trips in Spain and I’m looking for support with marketing and lead generation. The goal is to attract UK clients who will book a hiking trip.
For each confirmed client booking, I will release a milestone payment of £60. This is a fixed fee per completed deliverable (a booked and paid client).
Tasks may include social media promotion, outreach, community engagement, or other marketing approaches — I’m flexible on how you achieve the result.
This project is ongoing, and there’s potential for multiple milestone payments if you bring more than one client.
