Hi, I am an architect based in the Philippines. I am using Revit Architecture 2011 for almost 5 years and I am happy to help you out in your project. We have the same work flow here, from cad files we convert it to revit for 3d modeling and construction drawings, but normally we start our projects directly in Revit with hand sketches only as basis. We also do 3d families and renderings (Lumion, 3dsMax, Revit Render) should you have any requirement. It normally takes us 1-2 days to complete a model of a house, depending on the scale and size of the project. For the payment, it is negotiable, we can do it on a per hour basis too, or package. I use skype, viber or google chat for communication with my past freelancer clients. Hoping to work with you soon. If you have any questions, please let me know. Thank you.
Best regards,
Arch. Czarina
