Autocad works hourly rates

Good day,
I would need people to support with electrical drawings on Autocad, most probably on an hourly basis with one or a few projects from times to times.
We modify title blocks, to translations, add folios, do specific wiring and terminal blocks etc ...
Also occasionally mechanical drawings (cabinet layout modification, add dimensions, translation)
Important also, we do PDF assemblies (publication) with all folios assembled into a single document.

Essentially customize existing projects.
We are supplied with DWG sources and PDF comments, most of the time.

Please provide your past experience in similar works.

Thanks

Jean-François
