As another newbie to the sport, I had been pondering the same questions.
I have noticed stalking syndicates being advertised but no fees mentioned and presumed this is, quite rightly, a way of keeping financial matters confidential. It does however, prevent some people from requesting more information as they feel they don't want to appear over/under whelmed by the reply.
I too have read some nightmare scenarios where people have been ripped off not just with stalking rights, but also with paid stalking and DSC2 outings. It has made me very careful and I did a heck of a lot of research before booking my first ever paid stalking ( only 2 weeks to go!).
It would be great if there was some kind of table with average prices for stalking the different species/sexes, for stalking rights on certain types of land and for prices of decent DSC2 outings.
Personally I found that, by posting on the forum, lots of people PM'd me and gave some fantastic advice and information and I will be forever grateful.
Hopefully, someone will PM you and give you some pointers to answer your questions.
