I never price any job till I see it.
Absolutely! (With rare, predictable exception. I may give a range.)
. . . not required to have a permit also told to customer.
I was waiting from the OP to see if anyone mentioned permit and inspection, as I was ready to. One can do a safe and functional installation for much less cost than one that will be inspected.
This has been proven out by the sheer amount of discussions we've had in the "how and where can we get around or avoid the insulated-neutral requirements?" pool and hot-tub electrical-supply threads.
A completely-compliant, permitted and inspected hot-tub installation can cost twice as much to do as one that was done with even UF all the way, and I've seen much worse than that, like NM and no GFCI.
Nonetheless, there's no way to price a job over the phone. At the very least, you have to see the length, routing, and tub requirements. Then there's the service size and headroom, and breaker space.
You may have an outdoor panel 20 feet away, or you may have a 100' run under or around the house, or to a detached building. There's the aforementioned earth/pad equipotential issues, service receptacle, etc.
However, Charlie Bob, having said all that, the previous job you mentioned in your opening post is probably the best ruler of all for you to use as a comparison yardstick for materials and labor. Oh, and permit/inspection.
