Advanced Guest Posting

I have looked through some plugins and cannot seem to be able to find the right one.

I am looking for a plugin that allows guests to make blog posts. This is easy enough, however the guest needs to be able to choose from a preset list of categories for the post, and two other preset dropdown menus.

Is there a plugin that will allow a guest to make a post with a description, category, and a couple other custom dropdowns (selects)?

Thanks!
