concrete slab

I am looking for an experienced contractor to complete an installation project for a medium size concrete slab. This slab will be approximately 100-500 square feet in size and will require the use of rib and block aggregate. The desired thickness of the slab is undecided so far, but could range from 4 - 8 inches. If you have the expertise, knowledge and tools to complete this project, please let me know. Thanks!
