Right now I have 2 restaurant suppliers in town that refer me almost exclusively. Any other ideas on businesses that sell direct to consumers that would benefit from a reliable electrician to refer to their customers (other than general contractors and other trades)?

from what I have been findinf out. realtors and mechanics are good for referals plus church goers

Hi there krstarkie!.
Oddly enough, I have a barber that used to throw a lot of work my way, when I was an EC.
You'd be amazed how many people actually ask thier barber if they know of good trades people.
Besides I rewired the lighting in his shop when he first moved in there and I gave him a good price on the job, so he's more than repaid me for the favour.
