pirate backdrop

hi the project i have is a youtube channel where i play saxaphone, have a green screen backdrop that needs some kind of pirate effect or background to go behind my playing music. Do you do VFX backdrops, id say something that is not just the same all the way through but then again not to complicated that will take away from the saxaphone music playing ill be doing in the fore front. Some kind of pirate background with a few things happening. Let me know roughly what something like that will cost. Dont have any images to show but it will literally just be me playing saxaphone dressed up like a pirate with a greenscreen backdrop.
