What kind of wood should I use for a platform that holds 200 lbs

 P: 368 I am making a flat platform with 4 leveling feet that can hold a heavy duty blower which is around 200 lbs. The platform is 21.5" x 22.5" as shown in this image (let me know if there are better designs): I thought about using 0.5" steel plate but with these dimensions, it will cost me $200+. That is why I decided wood would be a good option although I am not sure what type of wood to use. What I need is something strong, will dampen vibrations from the blower and costs less than$100 (the cheaper the better). This will be indoors and will be a raised platform, I was thinking of using Heavy Duty Vibration-Damping Leveling Mounts. I heard that I can use 2x's to build a platform. What dimension 2x's should I use and I am guessing I would put them side by side to form a platform similar to hardwood floors?
