that seller is larry davis and i doubt he will charge too much for shipping it... it will fit standard shipping tube that he can get at the post office so my guess is $30 for shipping air.
the problem will be the width of new fingerboard. i don't think it matches the one you have...
i understand the approach with snapping the fret in half by small drill bit - as i see it it would go :
1) sanding the finish off the top of the fretboard
2) making a hole through the middle of each fret
3)using high quality stainless dental pick to get them out in halves
i think that unless you have access to steady supply of high quality cheap dental instruments you are out of luck with this idea...
it is my guess that you could remove binding only from the bottom of the fingerboard and get them out through there...:
1) remove bottom binding and scrape the varnish off the top of the fingerboard
2) get the frets out just like paul suggested
3) glue the binding back...
etc...
yet another approach to your problem would be to get bass that is already fretted
