How the heatmap is built

Every cell in the grid above is the count of firms in (place × hourly-rate tier). Firms are placed by their published hourly rate; those without a disclosed rate are not plotted.

Top company names per cell are surfaced by Value Score - a weighted blend of affordability (50%) + rating (35%) + review volume (15%).

The "Best" ribbon marks the cell in each row where firm density, ratings, and affordability line up best - the densest, highest-quality combination.
