I should be receiving an offer from a big Corp for an AE role. What's your experience in negotiating during this early stage?

So I've been working for a start for a little over a year. Started as inbound sales rep, moved up to AE a few months ago. A close friend made an intro for me to their old manager at a pretty Suite company. Here I am in the backend of the interview process and waiting for my offer letter.

This position will require me to relocate to a new state where the cost of living is much higher. I am prepared to pitch my thoughts and get a solid package to come on board.

I just want to get any advice, thoughts, prior experience you can shed some light on as this is my first time going through this process.

How do I gauge a great base (I'm at 50k now), do I ask for a signing bonus, etc?
