Ditto what LJ said. Make a blog or website. You can do both of these for free.
www.webs.com lets you do the website for free.
www.blogspot.com will let you do your blog free. Cattle.com will let you put your site address under their links page for free and everytime you update your site it appears on their Directory Updated sites page which I know gets a ton of hits and lots of people visit it. We noticed roughly around an average of 100 more hits easy, once we added our link to our website on Cattle.com. Also add your link to SteerPlanets breeder directory. This is all FREE and helps a TON. Also get some real good pics of your calves and put them on your computer. Make a homemade flyer/ad of your own, including your info on the calves and yourself, along with sale date/ price(if you want, some dont want price advertised widely). Also include if these calves are related to any winners, donors, bigtime sires. You know any recognizable/notable relationships with some more of the famous cattle, even if its just a county fair champion. Get permission from the directors at the shows and put up your ads. State Fairs, County Fairs, late summer/spring jackpot shows, fall shows, and even some of the early winter shows. Early winter shows also usually have consignment sales for calves that have been shown the day before known as a sale/show, then the next day is the jr. show. So thats another option for you. Sorry for going on so long. Hope this helps
But the most important thing is that you get that "GREAT SHOT", that accurately represents your calf/calves at the LEAST. When comparing where to go that weekend to look at calves to buy, your calves have to beat their calves in the pictures. So GET GOOD PICS

If your calf is better than theirs in the pic, you're most likely getting the business that weekend.
