Welcome to quilting, you will enjoy it. One way to save on rulers is to use coupons for them or look for them on sale. Hobby Lobby, Joanns and Hancocks have sales all the time. Also check online for sales, Missouri Star Quilt Co. has a daily deal that has fantastic prices and specials. You do need a few basic rulers such as 12x12, 4x24 or 6x24. Good luck.
