"OK, let's discuss the possibility of your having a research assistant.  We are prepared to offer you a paid graduate research assistant (minimum wage; sorry, the wage level is not negotiable) for ONE calendar year. Is this acceptable?"

Your response: 

1. "Yes.  That will be fine.  Thank you!"

2. "I'm sorry but you'll have to do better than that!  And upon reflection, I think I'm going to need a bigger salary; after all...the cost of living..."

3. "I was really thinking of having the funding for a 'longer-period'...Say, three years.  I'm starting a big research project that will last at least three years."
