Hi Jana as suggested in some of those post you may have read you may want to carry out a market test with other companies as to what they are charging, particularly in your area. Prices vary in different parts of the UK and therefore cannot be applied globally. What you will find is lower and upper rates to work with but don't be misguided by this. Other factors will determine what rate you will charge. Questions that you need to consider will included whether you are doing the work or do you have staff? Costs for overheads, equipment, insurances etc., it goes on. Let us know how you get on.
