Web hosting and banking costs can be rather high. That has a lot to do with why I closed my online quilt shop. Getting your website to come up in search engines can also be a real challenge and if it doesn't come up in search engines you're basically wasting your time and money. I would say if you don't have at least $100 a month to devote to web and banking costs plus the time to devote to keeping your website updated you may want to rethink the whole thing.
