Tell them you can engineer/design their electrical plans for a set fee that you will take off a portion of at bid price if they award contract to you. You can build your bid to make back this discount if you so desire then you get the job and if you don't you still get paid. If they are agreeable you could do it for T & M but I find this is usually a headache and they will want a ballpark. You could also establish a price for cans, outlets etc and tell them the prices for Kit. hr's etc is extra $$$ and the outlet count is the price if they want to walk it and add as you go you make out ok.
