Profit Division

A friend and I are starting a business which will require $60,000 in start-up funds (we will be importing European antique furniture and selling in the US via a website and at regional/national antique markets). I will invest $50,000, and she will invest $10,000. We will be dividing work responsibilities 50/50. I will be providing storage for our large inventory in a new barn we will build (our family had planned to build a much smaller barn in a few years, but to accommodate the business, we are building now - increased cost of enlarging our original planned building to accommodate our business storage needs is $40,000).

Given this funding/work structure, we would appreciate recommendations on how we should approach the division of profits, etc. Many thanks.
