We don't have a published price list for this page, and we're not going to make one up. What we can tell you is what drives the number up or down on a typical La Puente install: whether the existing wiring is usable, whether the header needs reinforcing for a heavier opener, and whether your current track and springs are original to the house or already replaced.
La Puente's median household income is $84,811, lower than the $96,234 median across the rest of our service area. We mention it because it shapes the kind of job we see out here more than the kind of opener we sell - most homeowners want the unit that works for another couple of decades, not the one with every feature, and that's a reasonable call on a house this age.
If your opener still runs but the chain is loud or the remote range is weak, that's sometimes a $40 part, not a new unit. We'll say so on site rather than sell you a replacement you don't need.
