I would suggest you adjust expected seed round to around 1M as a long shot assumption. Lots of 250-500k seed rounds out there right now because market is inexorably tight.

For salary, I would try not to take a penny or to take as little as humanly possible. You need marketing, sales and engineering. Your goal is to grow the business with that money, not necessarily reward yourself as if you’ve “made it”.

This isn’t to say you shouldn’t be paid, but you should use those funds as judiciously as possible, and reach profitability as soon as possible.
