A typical cello neck with a broken button. After it was lined up and glued, I pinned it from the inside. It also had a saddle crack that I glued from the outside.

Another broken cello neck. At this time, I had about 4 or 5 cellos with various types of broken necks.

Here is a cello where it was previously glued in at the wrong angle, not centered, wrong projection and the neck wasn't even glued to the button. Since I work by myself, I needed some way to hold it steady while I unglued the neck. These inexpensive cellos do not have their necks fitted properly in the first place and they are not worth removing the neck and fitting pieces of maple or spruce, so I just flushed out the old glue, added new glue, aligned the neck and eventualy put a pin from the inside to help hold the neck in place.

Here is a cello neck that was sheared off. Since it was an inexpensive cello with centimental value, I repaired it without doing a neck graft. Here are some work in progress pictures.

I fix a lot of cello necks but usually don't take any photos because it's fairly straight forward. Here is on where it was broken at quite an angle.

Tip for measuring a neck to make sure it's in the center.

Here is a another cello with a broken next. I have fixed hundreds of these. Three screwed pins at the correct angle and lenght works the best. Also clamping so that you are not fighting gravity makes things a lot easier. Once the end grain has been flattened to match the fingerboard, it's dyed black and sealed.

From your description it seems like it's a fairly minor repair. Without seeing the cello it's diffucult to give an estimate. If it's a very small crack just gluing it might be sufficient, my guess would be $35. If it's a large crack it might need to be glued and pinned which would cost about $75.
From your description I'm guessing that the heal of the neck is cracked. If there is no visible crack and the fingerboard height has moved then the neck could be pulling out of the body.
Usually a cello neck can support the pressure from the strings unless there is a flaw in the wood, it was dropped or damaged during shipping. The reason the fingerboard needs adjusting is because of the crack, once it's repaired the string height should be correct.
If it's a student cello, the best way to repair the cello neck is to glue and pin it and after that type of repair the neck is very solid and secure. A repair for a student cello is about $75 and because I'm busy it takes a week or two to repair it.
