Hey,
This side Shubham, currently a Budding Architect. As I belong to the field of Architecture, so working on Autodesk Architecture is mandatory for us. So, I have my hands well settled on this software and also It won't be hard for me to understand your plans.
I just can't be sure about how much time it may take for me to draft it as I don't know the level of work I need to do. If you could upload the scanned copy or jpeg image of your hand drafted work, then it's gonna make me clear up my mind. Hence, I will be able to tell you the exact amount of time its gonna take for me to finish off your work.
And the rest we can discuss afterward.
Hope to get a positive kind of response from your side.
Have a nice day.
Thank You
