What I want to do is build a walkway that goes through the treed area,
over the marshland. I want it to go from the side of my house all the way
to the end of my property where I will put a screened in gazebo. This is
probably a 75 foot walk.

What type of company would build something like this? Can I call a deck
building company?

I'd try a deck builder. You may want to check if there are any regulations
abut building around the marsh if it is deemed to be "wetlands". Even though
it is your property there may be some limits to what you can do.
