The numbers
AES is the proof.
What this site cost. What it would have cost the traditional way. And what that difference means for the digital projects your school or trust is currently outsourcing.

Total project cost
Logarithmic scale — the gap is bigger than it looks.
log₁₀ scale: log₁₀(27500)=4.44, log₁₀(1240)=3.09. Still 22× cheaper than the agency baseline.
Cost per deliverable
Agency mid-range vs founder time at £150/hr.
Time per deliverable

What this means for your school
Schools are still buying what they could now build.
AES training shows your staff how to do this work themselves. One in-house day pays for itself the first time you replace an agency quote with an internal weekend. The Revision Planner and Feedback Tool are the proof that it works at school-grade quality.
