If I made such a store I would use the web hosting model, you have a super cheap plan and if you want more feature you pay extra, I would care about your sales similar on how web hosting do not care about what you sell from your website.
Why is web hosting so cheap and you have so many options? Because of competition, allow competition with at least 5 stores and you will see different prices and features.
