I don't know what part of Arkansas you are from, but if you are close to any Armed Forces Base, (like Barksdale Air Force Base in Shreveport) families that are being transferred overseas are often getting rid of lots of things. The base closest to us has one day a month that they are allowed to hold yard sales and there are so many that you almost can't make them all in one day.
You might also put a note up on boards at grocery stores, local colleges or in the paper under "wanted to buy". You might also check scratch and dent or trade in sections of appliance stores.
As far as furniture, looks like the closest Ikea is Dallas, but it might be worth the trip with a U-Haul. They have great stuff at bargain prices. You can also order from them.
Be creative and re-purpose things. Get a twin bed and use it as a couch during the day and as a bed at night. When you can afford another bed, then you still have a couch or use it for guests. You can always use TV trays with chairs until you can get a table. Focus on the most important things first, like a fridge or stove. The Laundromat is a drag, but it beats not having a fridge.
