Tool Comp G41/G42 Program question

Gentlemen:
I have developed a cutter comp program which has as an input an
uncompensated G-Code file, and outputs a compensated version of that
file. The user enters the Direction of offset and the Amount of
offset along with a New File Name (maybe just add a ".C" suffix to
the original filename) and the compensated file is then generated. My
testing of this program shows it to be OK from the testing already
done. However as the program now stands, it does not lookahead far
enough to prevent "gouging" of some later block.
The remaining development would be the lookahead, maybe 50 blocks
or so, to establish whether any of the succeeding blocks compensated
path would interfere with a given block. Of course this will require
some time and effort to do successfully.
So my question is, "Can I charge $25 for this program to cover all
the back-and-forth E-Mails, and other headaches etc?"
You can reach me at jcc nospam @.... Correct the obvious!

Looking forward to your comments.
Regards,
Jack C.
