What's a good site for inexpensive airline tickets and rental cars? They plan on April 26 & 30, travel days

My best friend and husband are flying down for a job interview for him, and possibly relocating, which makes me, and them very happy. It's from Detroit, MI to Jacksonville, FL. The return trip can be from Tampa, FL, if it's cheaper. We want the least expensive way to go. Any suggestions? There are so many sites, not sure where to start.What's a good site for inexpensive airline tickets and rental cars? They plan on April 26 %26amp; 30, travel days
