yes you can and it works, but you must show what value you are giving as price is judged on all services being the same. by having your message show and tell prospects that price is not the thing they should use to choose a carpet cleaner you will stand out.
USP is about how you are different and why. most prospects dont know any other ways to judge a carpet cleaner thats why JP wrote the consumers guide. educating prospects. price without a message will not work and thats what most that put prices on marketing dont understand
Also selling by packages will sow a seed that all services are not the same. you will be surprised how different each carpet cleaners service is. thats why prices differ as well as high overheads.
why should a customer pay with light soil and no stains pay the same as one with high soil and loads of stains. or empty rooms compared with ones filler with stuff they want moved? This is what you need to get over in your message.
BTW there is nothing wrong with a basic service (just cleaning carpets) after all when they phone this is what they are asking for. furniture moving, etc should be extra cost. time is money.
So when prospects and other carpet cleaners judge you on price without details then it like comparing apples with oranges.
BTW the view that low price equals poor service is bad. and high price equals good, is rubbish. this goes to the heart of what I am saying that value is key. saying someone that is low price is uneducated in cleaning is wrong. Prospects will take it as said that anyone that is in business is a professional. thats why scammers get away with what they do.
its basic economics that market forces drive price. dont take my word for it. do a split test. which you should always be doing. once you get a bench mark you can try and better it. drive two different message to two different pages. this way the market will tell you which is best. One reason adwords is so great.
below is a very old example of how to show value, your welcome to use
