Welcome from Washington State. I purchased my sewing machine at Costco for about $175. I can do a lot with it, including machine quilting. It also has some special stitches that are fun to use. I would check out Leah Day online. She is self taught. She specializes in machine quilting, but she is a great teacher.
If you go to JoAnns or a quilt store, you can get a packet of fabric, called a charm pack, that is already cut in 5 inch squares. Then, just start sewing them together. You will end up with a small lap quilt or table topper.
My greatest piece of advice would be to have no fear. If you make a mistake, so what! You will learn lots. Just have fun!!
