My bantam lays eggs about half the size of a large egg from King Soopers. You can look around BYC and chicken blogs for some pointers, and My Pet Chicken has a very good breed chart in their book, which you can put on hold at your local library. Also, they have an o.k. 'breed selection tool'. They might even still be selling chicks. Here is a link: http://www.mypetchicken.com/chicken-breeds/which-breed-is-right-for-me.aspx Many other chicken books also have breed charts, which you can compare. Off the top of my head, I think some good heat birds would be Leghorns, Campines, and maybe an egg hybrid, since they are all slim? It's cold over here, so I mostly have to look for fluffy butts.
