Hi, I'm a Civil Engineer-CAD Technician from 8 years, thanks to two different universities.
I have a lot of direct experience because i worked for public and private companies.
I'm currently collaborating as a project manager for a construction company (residential/commercial buildings).
About your project i can make a "bill of quantities", but i need to know the location, plans, elevations, sections, materials and other details to give a good estimate.
Price and time depend to project complexity.
If you have some questions do not hesitate to ask.
Cheers.
