Visio Flowcharts & Excel Project Checklist

I'm in need of a freelancer who is skilled in designing both process and workflow flowcharts via Microsoft Visio, as well as project management checklist forms in Excel. The checklist should be of an intermediate level complexity, incorporating features such as drop-downs and validation. Prior experience in constructing Visio flowcharts and Excel forms is imperative to understand the project's need thoroughly. Proficiency in Excel functionalities would make tackling this task comparatively easier.
