steve,
ran into an old drinking buddy of mine last week he told me that a family member on his wifes side did the same thing some months ago, took out a 6 week advert in the local rag (£250ish) got a few jobs off it, one of which is a £100 weekly, 4 hour max, and now need to take people on. i'll try and get more info regarding equipment/insurance/pricing etc, can't promise as it will be all third party stuff. in the meantime,
good luck mrs easyclean
p.s does she do ironing
