Unfortunately you have just missed th two main poultry shows of the year which would have given you the opportunity to look at all the breeds and a comparison of the breeders birds also.
Maybe get some books form the library, look though, read about them, then perhaps a bit of internet research. Having decided which breed/breeds suit you best then I think it would be wise to join the relevant breed club, which generally doesn't cost all that much, and from the club you should be able to source reliable breeders of quality stock.
All the best
