Rob. Get yourself some long 8-10ft sticks from your local cabinet maker shop. Get 1" by 1.5" poplar sticks. Then get same length of quarter round moulding in pine. Connect both to make your own 1.5" stretcher bars. Use miter to cut 45 degree angles at your desired length. A little wood glue and nail gun and you can make your own for about .80 cents a linear foot.
If you are spending .80 a foot without labor they are probably costing you $2.00 a foot if you add in the labor.
That's a lot of work unless you just like to fool with wood.
Putting what I do aside ,Decor Moulding and a dozen other distributors sell full lengths from .45 to .60 a running foot.
