TSO Host for me too £4.99 per month but just the one site because I couldn't be bothered to build any more. It brings in quite a lot of enquiries but, as I have said previously, 80% is a load of rubbish...but then 20% is OK.
My leaflets cost me about £60 for 5,000 printed and delivered. My stepson is off from College, so he does one day a week for me at the moment in specifically targeted streets and he's very good. He cost's me beer money plus commission. A very good ROI.
I also do some very targeted canvassing that only costs me my time (but that's worth something too). Although it does get me out the house and away from Mrs Window Cleaner on a 'shopping at Sainsbury's day'!
Previously I have done Google Adwords and for me, it paid for itself and then some. This year I haven't bothered because I really want to compact my round and Adwords isn't the tool to do it.
