Well i would contact elder, Cristy collions, brad hook or someone like that and get their photos taken and then send it to a printing company, like Morris cattle company, their link is in the breeders section, and get them to make a full page add for each of your bulls, and give Them all your info, Th and PHA status, birth weights, sire, dam, any special stuff (like if mom was grand overall female at the NWSS) and then get those adds all over the place, your website, magizines(showbox, Maine Anjou voice, there are others but cant think of them), and send the photo of your bulls to the semen distributors and all the info and see if they will sell the semen. It also Helps a lot if you have a well known name or have some one with a well known name on the adds.
good luck hope i helped a little bit, if not tell me and i will try it again ;D
