Hmmm not sure how much I want to weigh on in this but some high level conversation about this...
Charge a fair price for your skill set, tool/equipment set, and customer base and make sure to clear your Labor costs and Rent/Equipment costs. If you are set up and skilled to do basic maintenance and repairs, great be that and be fair with pricing. If you are set up and skilled to do more intensive or specialty work, great be that and be fair with pricing.
As many have mentioned also, the $80 rate is definitely cheap for the Columbus market IF you are churning out quality work. Your average shop rate in the area is $105-$125 per hour so you may be selling yourselves short. As in retail, when cutting prices to get people in the door you often times find yourself serving a customer base that's only looking for cheap deals and scab fixes. It's like running $10 oil change coupons... you'll do a whole lot of oil changes and NOTHING else, and few if any of those people will become customers looking for more services.
As Cordell points out... there are a LOT of steps to making a shop successful from the guy answering the phones and talking to customer, to the guys getting greasy if there isn't communication and honesty you're in a slow boiling shit stew. We pride ourselves on being on of the best Independent shops in the region and work hard for that reputation, but even WE screw up on communication on a somewhat regular basis. Be honest with your customers, try to keep an open line of communication, and do your best to be fair in pricing while not slitting your own throat to "get the job".
