I like to keep things simple. There are two levels of cost, an hourly rate and a discount. That’s it.
If you require specific technical advice (requiring me to give specific information, develop code, remote desktop or similar) it is the standard tier.
If you only require generalized advice such as best practices, project overviews, initial introduction meetings, or similar, then there is a 50% tier at which the price is half.
Standard Rate£100/hour(includes all taxes)
50% Rate£50/hour(includes all taxes)
I take each client on an individual basis, and discounts can be negotiated such as a few sessions half price, or bulk-buying of hours up front.
