Suggestions for selling lamb

We've been raising sheep for 35 years. Instead of relying on the farm markets, I want to try to sell direct to customers. We can't sell meat directly due to Dept of Agriculture rules. We plan on selling live lambs and deliver to the butcher. The buyer would buy the live lamb and pay the butcher. The market is very very good right as there is a shortage of lamb. I thought we would sell about $30 over market since the market is so good. I also thought we should ask for a deposit before we deliver to the butcher. I work in a fairly large office building and I thought I would just pass some cards around during breaks, etc. We also have a diverse ethnic group of people in our community and I would like to post cards in the ethnic grocery stores.

Any suggestions or opinions?

I will also post in the "Poultry and Livestock" section.
