If you DO decide to take it on as a job dont be frightened of asking for the right money, also, very often people feel they're getting good service if they're paying for something rather than just feeding someones hobby. Years ago i was asked to clear a large warehouse of pigeons, i had no idea what to charge so i rang some major companies to get quotes, Rentokil wanted £1200 (yes thats one thousand two hundred pounds) to put two men on site for two hours Now i'm not saying everyone can charge that they can because they're a major player but it just gives you some idea,
