We're not going to put a number here that isn't tied to your actual door, because the range between a basic non-insulated single door and an insulated double with a matched opener is wide, and the honest answer depends on what's already in your garage. What we can tell you is what drives the price up or down on a job like this: door width (single versus double), insulation level, whether the opener needs replacing too, and whether the existing opening needs any framing correction.
Given the age of housing stock in this area, framing correction comes up often enough that it's worth budgeting for as a possibility rather than an assumption. We give a firm number after measuring, not before - a phone quote on an install job is a guess, and we don't like handing out guesses on something this physical.
Worth knowing before you call: if your current door is repairable rather than failing outright, we'll say so. Replacement makes sense when the door, track, or spring hardware is original and worn past the point repair parts exist for it - not just because it's old.
