Mapbox GL JS Developer for Webflow CMS

I’m looking for a developer with strong Mapbox GL JS experience to optimize a rental property search map built in Webflow. The current setup uses No Code Flow’s Dynamic Map component for Webflow and pulls from 2,200+ CMS property items. The search and filters work correctly, and performance is acceptable once users narrow the results. The problem is the initial map load: all property markers render at once, causing lag and a poor user experience. The primary goal is to add marker clustering so markers are grouped by zoom level instead of rendering 2,200+ individual pins on initial load. This is not a basic map embed. I need someone who can evaluate whether clustering can be added to the existing No Code Flow implementation, or whether the map should be rebuilt with a custom Mapbox GL JS + GeoJSON setup. You should be comfortable with Mapbox GL JS, GeoJSON sources, marker clustering, Webflow CMS, JavaScript performance optimization, and preserving existing search/filter behavior. Please include examples of Mapbox clustering or high-volume marker projects, your recommended approach, estimated timeline, and estimated cost.
