I'm looking into leasing some comercial/industrial space and setting up rehearsal rooms. I've got a meeting set up for some free bid'niz advice at a local college, and I'm going to look into a veteran's small business loan, and such. Obvious start up costs would include: the price of the lease and parking, equipment insurance, equipment, insurance in case someone gets hurt, construction for room divisions (as needed depending on the space) and acoustic treatments (other forum, I know), electrical work, permits for this work, air conditioners and such, lighting, music stands, furniture, security, and filing fees to establish the business. Obvious operating costs would include the lease and insurance, equipment maintaiance (or replacement if beat on too badly), phone bill, utilities bill, taxes, record keeping, cleaning supplies, advertising, light bulbs, trash bags ... Is there any words of wisdom anyone can give me here, or any glaring omissions above? Ultimately I'm planning a somewhat more diverse enterprise, but the primary focus will be rehearsal space. I know that a good business plan, and sufficient start up funds are essential to any business in addition to knowledge and hard work.
