Bicycle Beer Delivery Service

Hi there,

I'm trying to start my own business, on the side of work initially but hopefully it could become full time. I'm thinking of offering a beer delivery service by bicycle. Here in Portland, OR there's tons of breweries and tons of beer consumers. Many like me have purchased growlers but I always forget to bring them with me to a bar to fill them up. I'm thinking a delivery service where I pick up people's growlers once a month, fill them with a beer from that months brewery and drop them off at their house, all by bicycle.

I'm going with the bicycle option because I have an incredibly small amount of money to invest (under $500). It also appeals to my, and the other Portland hipsters, environmental philosophies. Perhaps the bike would be a unique feature of my company that people would like.

There's a ton of questions I have about starting a company though.
- I live with my in laws, having just moved to America. Do I need to make myself an LLC before I pick up a single beer or can I test the theory before needing to register as a business?
- If I register as an LLC is it wise to use my home address at the start, or should I pay a business service to use their address (especially considering I don't own the property)?
- Does anyone have any advice on how to collect payment? I'm thinking at the start when I pick up the growler, the customer pays me. This way I could start the business without a website and just use a Facebook page.

Any help would be greatly appreciated.

Thanks,
