Generally speaking, there is a little negotiation you can do around salary and benefits when/if you reach that point in an interview. That said, many companies will give you an offer and you can either take it or leave it. Showing up with a 'package' offering like this will get you laughed out of the room.

You get laughed at and told to get out.

Now, if you're an independent contractor you can start doing something like this but formatted a bit more official...
