Plugin Recommendation: Events, Members, & Store

I think it’s unlikely that anything like this exists, but in the hopes that someone has any ideas…I’m trying to find a plugin that can handle all of the following:

– events, such as workshops
– products for sale (which can either be tied to a workshop, or bought individually) Example: the workbook that needs to be bought in addition to the workshop event ticket
– membership levels, whereby different membership levels pay different prices for both events and products

I can find plugins that handle each element of that, but not all at once. We don’t want to have separate checkout process for an event and the items that go with it. Has anyone seen anything like this?
