You will not work as fast as the professional

All I can say is, having done a decent DIY job on several rooms, with all
the right tools, that I could only average 2 sq ft per hour, all told from
start to finish and grouting and clean-up. So 220 sq ft would be weeks of
work, at least for this perfectionist, but it may be for you, too.

Depending on what your time and knees are worth, you may want to price the
commercial installation.

Sometimes its not the money but the joy and the pain of doing it yourself,
hence your 2sf/hour. Using your numbers, he will be on the floor for almost
three 40 hour working weeks! :-)
