A putting green is the most precisely built surface in this trade. The ball tells the truth about the base, and a green laid over an uneven pad will not roll true no matter what the turf costs.
An artificial putting green in Miami is a small area with a large specification: a shaped, compacted base, a cup liner or a synthetic cup system, a fringe or chipping collar, and a turf with a low face weight and a tight stitch so the ball rolls at a consistent speed. Published South Florida bands put putting green material at 12 to 16 per square foot and labour at 15 to 20 per square foot, the highest per-square-foot prices on this site, because the area is small, the base has to be shaped rather than flattened, and the tolerance for error is measured in millimetres.
A lawn base can be flat. A green cannot: contours, breaks and a shaped apron are the point of it. The build compacts an open-graded aggregate in shaped lifts, checks the surface with a straight edge and a level, and only then lays the turf and cuts the cups. In Miami-Dade the rock is often shallow, so the shape is built up rather than excavated, and the same base has to carry away wet-season rain without turning the low side into a puddle.
Most backyard greens run 200 to 600 square feet. Because fixed costs spread over a small area, the per-square-foot price is not comparable to a lawn quote, and a green that seems cheap per square foot is usually a flat pad with turf on it.
Putting turf is a short pile with a tight stitch and a low face weight, usually polypropylene or a nylon blend, and it is chosen for roll consistency rather than for looks. Infill is fine silica sand, brushed in to weight the surface and set the speed. In South Florida add ultraviolet to the checklist: everything at 8 and above on the EPA UV Index scale is very high to extreme and Miami sits there much of the year (https://www.epa.gov/sunsafety/uv-index-scale-0, HTTP 200), so a stabilised fibre is not a premium, it is the minimum.
The wet season runs roughly May to October, with short heavy afternoon rain (https://www.weather.gov/mfl/, HTTP 200). A green needs a fall on the apron and a base that passes water, or the low break fills and the cups silt. Shade helps twice: it makes the surface usable in the afternoon and it slows the UV load. Where a green sits under canopy, a rinse and brush routine keeps leaf litter and mould off the putting surface.
A green earns its price in reps. The alternative is a drive to a practice facility, and in Miami traffic that is a real cost in time. A green with three or four hole positions, a fringe for chipping and a few metres of fairway apron covers most of what a recreational golfer practises. Ask for the cup layout and the fringe width in the quote, because those are the two things that make the green usable rather than decorative.

Usually a week or two for a backyard green. The shaping and compaction of the base is the slow part, and the turf and cups go in quickly after that.
It will if the apron is graded and the base is open-graded with an outlet. A green built flat on compacted fill holds water at the low break, and that is where cups silt and the surface goes soft.
Yes. A fringe or chipping collar is a common add, and a synthetic bunker is a separate build. Ask for both priced as line items so you can compare offers on the same scope.
