I´ve re-read your post and noted you want a B206 or R44, and i think HTA only has 2 AS350B2, but if you contact them they might be able to get you a B206 or a R44 from another company. In the North: for Bell 206

For R44:
www.nortavia.pt (both from the Nort of PT).
If you need anything else you can PM me, has i live in PT.
