SharePoint SetUp and Process Flow Design

We are looking for an experienced SharePoint developer to set up the system for us and create a complex inventory management workflow. There will be multiple revisions of the workflow by us as the process is tested and refined. Ideally, scripts would be created that would automatically trigger data uploads to BrightPearl, our backend inventory management system. Examples of workflows you have created in the past are helpful to our evaluation process. Also, fluent spoken and written U.S. English are a requirement.
