can certainly do it at Sherburn if you book in advance - I did it there over 2 weeks, which didn't seem overly intensive, though it was hard work.
very well equipped a/c too, (HSI, RMI, 2 radios etc).
also waterlogged runways not a problem now with the hard strip. For quite a bit more money I'm sure multiflight or LFS at LBA will also block out a week for you with enough notice.
good luck wherever you do it
