on Island researchers generally charge about £10/hour - photocopies from Manx museum, are 80p/page but they will not generally provide more than a single will by post (it takes a minimum of about 20min/will to find + copy) - 19th C wills tend to run to 10 or more pages in length.

If you have lots then suggest you find an open FHS and start hiring the films - check also on my site if I've already summarised them(mostly 18th C)
