Very Part Time Bookkeeping/Office Management

We're a small sailmaking company that needs a parttime, INHOUSE bookkeeper for typing invoices & paying the bills & staff. You can pretty much make your own hours (12 to 20 per/wk) & let me know what to pay you. We're hoping to find a retired business person who's on the ball & would like to have some purpose now & then. It's a nice environment. The staff is pleasant as are most of the customers. There's no A/C & you'll freeze your butt off in the winter. Still, it ain't bad.
