Hi,
I claim I am expert in Code thing, beside long years of experience with drawings and modeling of building.
actually, recently, I have done complicated CAD code for PCB line production for a factory in India, May I give you contact in case you are interested, also I have finished a model for 30 floor high rise building with layers of details for further section for a Britch company, also I can give you contact in case you are interested.
one more thing, if we agree for code, I don't deliver the source code, I only deliver complied one, which will run faster but you will not be able to edit it, also I need to know more details about the project since I really prefer deal as a whole project cost not hourly.
Thanks.
