Database Repair and Image Restore

Website: [login to view URL] This website has a database that continually crashes every few hours. The hosting company, HostGator, has been good about restoring the database when it crashes, but it will be down a few hours later. I need help getting this PERMANENTLY fixed. It may be an issue with the Wordpress theme itself - whatever it is, I need help fixing it, and as soon as possible. In addition, some images were removed in the process, and that is throwing off the theme (see the background, header, and footer of the website). Identifying the missing images and restoring them is also required. I look forward to working with you!
