Thank you for the numbers.
It was implied that this was a project. I am more than capable of gluing a fingeboard and cutting the neck to proper dimensions. I am not paying a luthier over 2k to work on a job that can be done by anyone skilled with tools. I called 3 different places and all of which they ballparked at least this amount maybe more. I am sorry, at that price I will just buy a new bass.
I am not a luthier and while there are a few setup and minor repair related things that I'm comfortable enough with tools to take on myself, i realize that the end result will totally be my responsibility and/or my fault.
That said, there are some things that only accomplished double bass luthiers, some who you have basically managed to insult here, have not only the tools and the forms and the supplies, but also have done the research and have the experience based wisdom to know how to do. True, it may be hard at first to know who in this forum has that true wisdom and who doesn't, but let me assure you that you and I are exchanging messages in this thread with true expert double bass luthiers.
There are a number of things not mentioned so far in this thread that are subtleties, yet absolutes of double bass life, which you may have no idea about. Unfortunately you may find out about many of them too late...
To save you some anguish in case you don't already know about it, let me mention what may be the most important subtlety in your situation, which is using hand formulated hot hide glue as your adhesive, specifically not using anything else that you may be able to buy in bottles at a store. If you use hot hide glue properly, with few exceptions no matter what you do wrong, it can be re-done correctly with minimal waste and damage. If you use any other glue, you will spend more time trying to clean that other glue from anything you have to re-do, in order to have healthy joints, than anything else you do.
Hot hide glue requires some simple inexpensive equipment, the powdered adhesive itself, water, and a lot of testing to get good experience before using it on your real project. While it may sound tedious, learning to use hot hide glue with musical instruments is a key to success, plus hot hide glue works well with most other woodwork too.
If you treat the luthiers here with genuine respect, and maybe drop some ego, you can probably get a lot of very valuable hints and help. We are here among giants, while they definitely don't advertise themselves that way.
