PAUL...here is part of something I saved that addresses your question. I wish I were more computer savvy and could put up the pdf file in total. Hope this helps. Note the "assumption" on cost of fuel.
Custom Rate Survey File A3-10
Many Iowa farmers hire some custom machine work in their farm
business, or perform custom work for others. Others rent machinery
or perform other services. The information below is based on a survey
of 187 Iowa farmers, custom operators, and farm managers. For each
operation, the average rate from the survey and the range are shown.
Thirty percent of the respondents perform custom work, 18 percent
hire work done, and 52 percent indicated doing both.
Values below are rates expected to be charged or paid, including
fuel and labor. The average price for diesel fuel was assumed to
be $2.25 per gallon. This rate schedule is intended only as a guide.
Actual custom rates may vary according to availability of machinery
in a given area, timeliness, operator skill, fi eld size and shape, crop
conditions, and the performance characteristics of the machine being
used. Machinery rental rates can be estimated on the back.

The figures shown appear to be over some sort of range. Moldboard plowing shows 10.00 to 18.45/per acre. My gut feeling is that 20-25/acre would be minimum. Distance to job?? Drive or trailer your equipment?? Can you get any idea of what prevailing rates are in your area??
