Hi steve
guerrilla marketing is about low cost marketing, PR based, so its great for carpet cleaning. as with JP it moves so easily from product to product or service to service, so don't pay loads of money for anything that carpet cleaning based as you might get the same info cheaper from another area.
one guerrilla idea that i have been thinking about is a billboard van, let me explain our vans are advertisement for our business, so why not buy a second van get it signed wrapped and park it each day at a local junction around our local area? how many times have you have someone say i got the number from your van?
regarding to cost, compared with the yellow pages i think this would out perform it. I have spent over £13k over the last two years with them and not got the return that i wanted. so if i just spent say a few thousand get a van that had flat paintwork and got it wrapped i estimate it can be done for about 3K
also the van could be used for other things. unlike YP if it does not work you just remove the signs and sell the van.
my main carpark in town chargs just £7.50 a day to park, and i think that thats got to be cheaper than paying someone to drop say 1K leaflets
