There's a lot of free information online on this site and bplans.com, including the startup costs calculator free online at www.bplans.com. Look in the business calculators.
You can also find more details on listing starting costs in my new book, The Plan-As-You-Go Business Plan, which is (at least temporarily) online now and in bookstores beginning August of 2008. Look in Chapter 4, "Flesh and Bones," for specifics on startup costs.
