You can download both 10m (1/3 arc second) and 30 m (1 arc second) DEMs from the USGS.  (They may even have 3 m (1/9 arc second) for you area).


You can then generate the contours from the DEM(s). 


Downloading is pretty straight forward.  David Wheelock wrote some excellent instructions a while back which are available in the OKGIS archive.

I put together all the 30m dems for Oklahoma a few years ago.   I can give you all zone 14 (utm).  Can't emial it though - its 500mb compressed.  It is in E00 format and gzipped. Email me if you want that much and I'll write it to a CD
