There's a considerable difference in prices between trout and salmon fishing on the Kola and secondly between rivers and dates (ranging from +/- £ 10.000 a week (all in)to +/- £ 2100 for 9 days fishing(flights and visa not included)). It all depends on the level of service, accommodation and guidance you're looking for and the size and number of fish you would like to catch (if all goes well

).
For my first Kola trip I've opted for the cheaper two river solution. I'll see where it goes from there...
PM me if you're interested in the details.
