Newbie-compatible ecommerce site

We are new to the idea of creating our own site using Word Press. It has come highly recommended. What we are looking for is some information on what E commerce app works best with Word Press. We have lots of questions as we are new to this but we will take it one step at a time. We are looking forward to rebuilding our site using Word Press. Check out our old site at https://www.hitmanhotrods.com
