565788 Improve 5 website graphics for my website

I am putting together a new website. My new website is located at [login to view URL] and you will see there is a graphic slider at the top of my website that displays five graphics. I made these 5 graphics as just temporary ones as I am not any good at this type of thing. I basically want similar graphics made with the same (or similar) information but presented much better. You can either use the same text and graphics as I have done or you can improve on it if you think it is wiser. Let me know what you think. The size is 700 x 270 I think. I am hoping for something great, something very hi-res, something creative and AWESOME. Thanks. Al
