flowcharts of allocation work processes

I am looking for the expertise of an experienced freelancer who can help me to create a series of flowcharts of my organization's allocation work processes. The purpose of these flowcharts is to visualize the allocation of work for a labour hire company. It is necessary to specifically define the individual tasks and activities, so I require the flowcharts to include a details of 3 work streams. flowcharts need to accurately represent the actual processes - and include the correct words and jargon.. there are 3 different work teams with slightly different variation on the same theme Thanks!
