School Site Blueprint Creation

I'm looking for a professional to create an accurate blueprint of our school grounds. This blueprint will be used to create an accurate record of the current site.

The blueprint should include:
- Buildings and room layouts
- Outdoor grounds, paths, parking, and sports areas

I have some existing materials to work with, including rough sketches, photos, and old plans. The ideal freelancer should have experience in:
- Architectural drafting
- Landscape design
- Proficiency in CAD software

Please provide samples of previous work and a brief outline of your approach.
