For new databases we normally give you a fixed price quote for producing a functional specification and a ballpark estimate for the whole project. Once we have done the analysis and design work we give you a completed functional specification with a fixed quote to complete the project. This allows you to see exactly what you will get and mitigate the risks of the project.
For fixes or changes to an existing database system we work on an hourly basis and provided regular reports on progress made and issues encountered. The hourly rate depends on the level of commitment- the more hours you commit to the lower the hourly rate. Please contact us us for more details.
