You can choose to engage me three ways.
You may prefer to work to a fixed budget. In this case, I will give you a clear idea of what I can deliver within your timeframe.
You may have a budget range in mind. We can discuss the various options within this range and we can then agree on what will be delivered.
You may have a project that requires ongoing collaboration. In this case an hourly rate is agreed upon depending on the length of the assignment.

My aim is to make it as simple as I can for you.
