Ask HN:Upfront Take and Vesting Schedule for Solo Founder

Hello HNers, I have been working on my startup past 1 years fulltime and have recently incorporated. My attorney suggested that I take 25% upfront fully vested for my work so far and rest 75% vesting over 4 year period. Attorney is legit guy and he does multiple XXXMil exits per year. So he knows what he is talking about. Wanted to check with the community, what are the typical norms for founder vesting. Another piece of info is that i am planning to raise some money in next 3-6 months. Thanks Shyam
