Well, as the error message says, you must pass a County instance in
the argument 'county'. Now you are passing the name of the county, not
the county itself. So, your last line should be
l = Company(name='xyz corp', address='56 b. street', client='G corp',
city = 'Walla Walla', county=c, dollar_amount =54000)
instead of
l = Company(name='xyz corp', address='56 b. street', client='G corp',
city = 'Walla Walla', county='blah blah', dollar_amount =54000)
where c is the County object defined before.
P.S. By the way, you mix 'County' and 'Country' in your example.
