If you are finding it hard to raise prices to a reasonable level to give yourself a reasonable income, then this may be of some help to you in planing future advertising campaigns.
Before any customer will hire your services there must be some sort of benefit that the customer will enjoy by employing you. This benefit can be several things, but the main benefit is not having to do the work themselves, in other words, they either can't do the work, don't want to do the work, or haven't got the machinery to carry out the work. So what they want is the freedom from pain of having to do the work themselves. The more pain relief they get from not having to do the work, the higher the benefit is.
High benefit low price offers will be snapped up by by people on low incomes that can't afford to pay a higher price. If the price is raised then the benefit they receive declines, so there has to be a balance between the benefit they receive and the price paid.
High Benefit high price offers have to be targeted to people that require the service, need the benefits of it, and can afford to pay the asking price. For example if a Brain Surgeon on £500,000 pa needed the freedom from doing gardening work he/she would be happy to pay much more to have a good job done, then would someone on a low income.
So when you advertise your services it is best to stress the benefits the customer will get from your services and not the features you offer. The features of your service are secondary to the customer benefits.
Managing the price of your services depends on the market segment you are going to serve. If you are going to advertise your services to everybody that has a garden, you will need to offer high benefits with lowish prices. If you offer your services to a targeted segment of the population, you need to offer high benefits with a price that will suit that segment.
If your customers get a low benefit or even no benefit from your service, then they will more than likely cancel it.
If you decide to offer your services only to a higher paying segment of the local population, then your profits will be higher too.
