The completion time of the project is purely dependent on the priced package you selected and it’s estimated size. You will be given a clear estimated completion time before the project is started. Often, if not always, the project is completed before this time.
A 50% deposit is always taken at the start of the project with the balance being paid upon completion. This payment can be made directly in to an agreed bank account, or even simpler, you can be invoiced via PayPal and pay securely through that service instead.
I always do my very best to work to a strict brief. This insures that the client is always happy with the final product. If in the rare occurrence that you are not 100% happy with the finally design, I will allow you to make any 3 minor changes to the site or design. These changes may include the changing of fonts, colour schemes etc but usually not changes to the physical layout of pages.
