As per ususal with any advertising, the majority of your enquiries will certainly be time wasters, canvassers, other sites asking if you want to be on their site, folk asking you if you can do an inspection on a house their interested in buying, then ringing you back and asking you if the house owner might prefer a niccy or other endorsed spark to do it? How much will it cost to rewire their house without you coming out to it, do you give discounts to single parents, will you give some money to bogus charities, do you want a loan, do you want a debt recovering, etc.
But on the other hand you will get some work out of it once you've dealt with all the non business related calls, when I used to advertise in Y.P. and T.L. over 6 years ago, I worked it out at around 18% genuine business enquiries with about a 40% turnaround, roughly about 8% of total enquiries. As there is always someone that doesn't know of a bonafide trades person.
I suppose you could buy a pay as you talk sim and a cheap phone and use that as a contact number, if the enquiries are non business related and sickening you. Then dish the sims and the advertising, and carry on with your word of mouth, and the timewasters will almost cease to exist.
