If you are fairly handy you could easily repair this with automotive or good quality wood filler. The refin is then a case of getting good quailty auto touch up paint that matches exactly then building up in layers unitl you can wet and dry it flat and polish it.
The fact that you've asked for help 'suggests' that you may struggle with this. Whilst I agree a luthier would sort it for you, it may cost as much as the bass is worth.... Especially if they suggest a whole refin is the only way to go.
Your profile doesn't let us know where you are, which is a shame. If you were nearby I'd have a pop at it for you, I need a new project.
Again if it turned out 5hite I would make a pickguard for it, which I could do anyway but would need the whole bass to get the dimensions.
What problems do you have with teh neck?
