I don't think I'm far off then. I've been charging £ for gardens including the first mole then £ for each extra mole. Farmers round here (SW shropshire) prefer to pay by the mole rather than the hour and don't expect to pay any more than £ a mole. I think I need to move to the South of England - £50 a mole and if the media are to be believed full of people who give up lucrative jobs like accountancy to be molecatchers and within a few months are turning away work. Give me some of that !
Out of interest where do you find you get most of your work from - word of mouth, yellow pages, website etc
