Hi, Welcome to woodcutting. Thoughts from an old timer. Starting in life, learning new ways of doing things, and aquiring tools to help get tasks done is exciting, fun, and dauntig. My advice is to look to the future when aquiring tools.
The saws I have used most in life for projects:
1. A circular saw with a speed square (also known as a skill saw). The square is used as a guide and the cut is straight on the board no matter what angle. I also use clamps to hold the board in place. (as a side note you can cut right on the pallet and not have to take it apart. Less work and more time for something else.) This has been my go to saw for many projects.
2. A compound miter saw. Mostly I use it as a chop saw, but there are times that the compound bevel and angle cut in one step has been a life saver. If buying an electric miter saw, go for the coumpound option with it for future needs.
3. A hand miter saw used mostly for 1 or 2 pieces of wood. Simple, quick and lightweight.
4. A Sawzall. Like a big jigsaw. I used it mostly for destruction at first but learned to make decent cuts for construction. Can be used on metal and wood.
5. For ripping wood in the field I made a jig and used a circular saw. In the shop the table saw.
You will need sawhorses and sturdy 2x4 flat boards to make a movable workbench which can be made from pallets.
Have fun with the project.
