Thank you for taking the time to reply,
At this stage of the game I'm just supplying a 3D model to start and if I am involved with the clients to make changes then will move to an hourly rate. I intend to charge a flat fee for the modelling service so am curious for example what you might charge in your area as a flat fee for the 3 level house with loft above garage? And an appropriate hourly rate to work with the clients doing real time changes and material applying.
In my eyes the value is there in creating a 3D model as it becomes the centralized source of information between clients, architects, designers and contractors not to mention all the hours saved and problems solved ahead of time. Since this is my first job, I am looking for guidance to set an appropriate amount.
