Depends largely if integral to the window unit or not, and how attached - can be as simple as slicing through the nails with sawzall, cutting in half to provide some space, and twisting out of position, then cutting new stock right size and inserting it with glue and caulk and painting to match - a couple hours work in ideal case. In-between cases can involve using a skil saw and hammer and chisel to remove only the front rotted part (or full depth if needed) from under the window, and fitting a new piece of stock to fit in - can be a couple hours work, can be twice that in some cases. In difficult cases, especially where it is part of the window frame, means taking entire window unit out, taking off bottom piece with sill, fabricating and installing a new one, and reinstalling the window unit and repainting - can easily be 5-8 hours work on an all-wood window, and up to about 15-20 manhours for a finely detailed heritage window. Generally, if the window unit has to come out to repair it, cheaper and quicker (though may not get matching appearancew with other window units) to just put a whole new unit in its place.

Also - redoing the existing sill rather than putting in new window unit is all some Window contractors will do - so getting a repair job done might take some calling around to find an old-school craftsman thype company which will repair units - or finding a Handyman or Carpenter - Woodworking with good ratings and reviews for this type of work who has the skills and patience to do the job right. Not rocket science - but tedious and indeeterminate how much trouble it will be until you get well into it, so many window companies will not touch it - both because of the indeterminate number of manhours to complete (so puts a wrnech in the scheduling of jobs) and because most window installers these days are window jockeys only - not actual craftsmen or finish carpenters like the old days.

So - cost - probably over $200 minimum unless extremely simple externally nailed-on sill; probably more like $200-400 range for normal size windows, and $400-600 possibly for built-in sills or larger windows.
