Are all electricians qualified to work with simple relay logic?
If you want someone to build products for/with you, then you should probably look for someone who builds industrial control panels - they may well not describe themselves as an 'electrician'.  I'll warn you that the're unlikely to be impressed by any kind of mad professor clutching simulations - they'll just expect a proper drawing of what you want and they'll make it for you.

You should probably see this as a separate task to installing things, which would be a job for an electrician - the kind of electrician you'll need depends on how complicated the installation is, not how complicated the product is. 

If you're trying to do business locally, then a local panel builder will probably know competent local electricians (and possible vice versa) - without knowing something about the product and where in the world you are it's impossible to be more specific.
