I think you'd have a hard time getting people to BUY the guide - after all, much rental information is available for free, such as in daily newspapers.
It would be more viable, I believe, if you charged people to advertise within it - not only landlords but other agencies that cater to people newly moving into rentals, such as cable TV services or carpet cleaners.
Good luck!
