Looking for someone to power wash and seal my driveway. Had an unfortunate incident after getting an oil change locally and need the stains removed.

http://www.completehydro.com/concrete_cleaning_concrete_sealing.asp I used this company to clean and seal mine ~ he's not the cheapest but uses a lifetime sealant verses the other bids I got where they only use a 3 to 5 year sealant. Additionally, he's the only one who when bidding told me he'd chalk the joints too. The joints need to be chalked or water gets under them and that's when the concrete will crack, separate, lift, etc. My neighbor used them too. We both have new homes with new concrete. I had mine down 3 1/2 years ago now and my concrete looks fantastic. No lifting, cracking, etc. My neighbors who haven't sealed and chalked their concrete doesn't look good.
