Please help me, I really need it?

Okay, I am in my final year at university and am required to write a business plan as a group project. Our group is basing their plan on beekeeping, well… kinda beekeeping. It’s based on a queen-bee rearing programme through a process of artificial insemination. I think we have a problem because the queen bees are the only product we are selling, at £25 each. Its impossible to write up a strategy because its so limited… Do you think that even though we are a voluntary organisation, we should still be selling other products and services? If we did there would be a lot of information from previous business plans to base it on. I feel so insecure about having a minimal strategy… if someone asked me to invest £000′s in their business so they could sell queen bees at £25/each I would laugh. But I doubt my group will listen to me
