Work performed in the shop is charged out on a time plus materials basis.  Customers are required to cover the costs of shipping, freight and travel expenses (if any of these are part of a job).  I don't mark up materials and/or any outsourcing costs like plasma, laser or water jet cutting.  These would become part of a job's cost as they are charged to me.  Hourly rates vary from $25/hr to $100/hr depending on what type of work is being performed and the machine tools used.  Below is a table of tiered pricing and what type(s) of work typically are included:

Hourly Shop Rate	Category	Work Description
$25/hour	Basic	Simple repairs and fabrication.  No setup or machine tools used.  Rebuild or fixing a router would fall into this category.
$50/hour	Standard	CAD/CAM work, machine tool setup and general shop fabrication.  This rate covers about 80% of most jobs.  Custom panels, boxes and enclosures.  TIG and plastic welding operations.  Product sourcing and evaluation.
$75/hour	Advanced	Electronic design and prototyping.  PCB layout.  Two dimensional CNC machining.  Setup, hold downs and fixtures.  Accurate lathe turning work.  Software design and coding.
$100/hour	Complex	3D layout, setup and CNC machining, expensive part modification and/or repair.  Complex fixture design.

No charges for travel to/from local customer businesses.
