It depends on whether you charge an hourly rate or a flat fee.I repair LCD monitors and laptops for a living and charge a flat fee of $75-200 per repair job. This can be anything from fixing a 17 monitor screen that has gone dark, to completely upgrading a laptop.Annually, it works out to an earnings of $30,000-40,000Obviously, some months are better than others.
it does not really matter; i presume you are writing a biz plan.you will list a desired take home pay per hour.put that into your income statement/proforma andbalance sheet and work backwards and you will havean idea what you need to charge.I can guide you further
