Fretboard replacement cost?

[uk_lefty]

Quick q for anyone who has had this done... I am considering buying a very beaten up vintage bass. At some point in the past someone has done a very bad defret. I think the board is unusable and would want it removing and replacing with a nice slab of unlined ebony or wenge. How much would I be spending on an operation like that, ballpark, please?  And are there any recommendations? I have emailed Shuker but expect he's a very busy chap, any other recommendations gratefully received.

 

Thank you
