I need a cover artist for a book and its sequel (e-book and paperback).

My book is a historical fiction book set in 1820 in the US. A young business man, Bill Rampy, rides cross country from New Orleans to Santa Fe to explore business possibilities. It appears Mexico's war of independence with Spain will soon be over with Mexico as the winner. Bill meets other business people in Santa Fe and goes with them to a trade fair in Chihuahua. / My idea for a cover was a man in his twenties on horse back followed by a pack horse. They would by riding across the prairie with mountains in the back ground. Or Bill and his horse (having lost the pack horse) could be riding in front of the governors palace in Santa Fe. In the sequel Bill returns to New Orleans, so the cover could be a wide variety of things we could discuss later.
