Build a map Land Plot using MapBox Library.

I have developed an HTML with css to draw a large land plot that has more than 3000 lands. This is already done but I would like to develop this further and show the actual plot inside a map (google map or map box) at the location of that land and it has to be interactive.

I have attached an example of what is needed and also an image of the land plot that was already developed in css and HTML. the attachements are large . so you can download them from there https://we.tl/t-UzdqK8tQkL

Please share the time and the cost to develop this.

Thanks,
Abdullah
