As far as I know, for tourists who want a 1-year visa, you must get a 'business' visa. I have just applied for business visa invitation - cost is $200 for 18-business day processing + $60 shipping of original letter(required); cost does not include actual visa. For my tourist visa invitation, I used www.waytorussia.net, and had no problems; so, I am using them for the business invitation, also.
