If you have a mismatch of all sorts of things then it will be harder to put a price on the treatments given. Sometimes it helps to check what the competition is doing and go from there.
Newly qualified will mean you are probably slow, but that doesn't mean you should be cheap. Concentrate on getting stunning work, accurate and neat nails and that will help you to build your client base and get your speed up.
Start too cheap and you will have difficulty in increasing your prices.
