You should charge what is the going rate for pups of similar quality. Are the parents of the pups Hip Scored and eye tested, have they done well at shows??? All these factors would influence what you would expect to pay for a puppy.
You should certainly not be charging more for colour, and as far as I am aware the eye colour you mention is not that in the breed standard, but pups start of with bluey eyse, so hopefully yours will eventually go brown.
You shold be breeding staffs that fit the breed standard and help to improve the quality of the breed, regardless of colour. As i understand it there are few quality dogs in the colours you have, probably because it is hard to get correct pigment in eye and also that to a large extent people breeding for colour take little notice of other breed stqandard requirements only being interested in colour, whcih is not a correct or responsible way of breeding. I am very glad that there is only one coat colour pattern in my own breed with only the shade varying. It is hard enough to breed a good dog withoutr being side tracked by colour and popularity of a give colour or not.
Also advertising pups for sale, as yopur post is likely to be taken, is not allowed on the forum.
