Residential and Commercial Construction Quoting

I need quotes for a small-medium residential project and a service-based commercial project.

For the residential project:
- The project is small in size and moderately complex
- I'm looking for a reliable estimation of the costs involved
- Experience with residential projects is highly desirable
- Bare lot sub divisions, sub developments, single home builds, concrete quotation, drainage, earthworks quotation.

For the commercial project:
- This is a service-based business, not retail or restaurant
- I'm interested in understanding the general cost of construction
- Experience with commercial projects in a service-based setting is an advantage
