Virtually no one, on a Sunday. And you'd pay through the nose for the service charge if you could find one. Honestly, your best option would be to buy a 5 gallon can and put 10 gallons of diesel fuel into your tank for now. Diesel is exactly the same thing as heating oil. Ten gallons would last you a few days until you can get a delivery without incurring a huge surcharge. Chances are if you could find anyone to deliver today they would just dump 10 gallons in as well, and would come back in a couple days with a delivery truck for the rest. (Do NOT use kerosene, by the way. It will destroy your system.) You likely will also have to prime your oil pump if you're completely out of oil. It's quite easy. I'm sure you can find directions either written or on YouTube if you need them. If you can't do that it will cost you a lot MORE to have them do it for you, on top of the emergency delivery fee.
Better option is to go to Speedway on W High Street (just past Jay's Bowling Lanes). They sell heating oil at the pump for $2.49 per gallon. Diesel pricing includes road taxes which makes price higher.
