Doing the whole CAD drafting yourself can be time consuming and laborious, especially when you run a one man show! A work colleague of mine recommended DraftAway, a company that does all the drawing and drafting for you. They specialise in drafting, design, and modelling 2D or 3D.
All you have to do is upload your project, you will then receive two email notifications, one reporting that they have received in and another notifying you of its completion.
For an easy process and always is fulfilled on time, Draftaway will do the job! Check out their electrical drafting page: http://draftaway.com.au/electrical-drafting.php
