I'd start by dividing the year into 250 work days. This means you'd have to win $200 per day.
From there, it's a question of volume, stakes and winrate.
$200 = (H * 2B * W)/100
where
H is Hands per Day
B is One Big Blind in $
W is Winrate in ptBB
Let's say you can play 3500 hands per day. H = 3500
Now let's assume that your maximum winrate is 2 ptBB. W = 2
$200 = (3500 * 2B * 2)/100
B = ($200*100)/(3,500*2*2)
B = $40,000/14,000
B = $2.86
Based on these assumptions, one big blind would have to be at least $2.86 (remember, we assumed a winrate no higher than 2 ptBB). If you were to play an even mix between $1/$2 and $2/$4, you'd be pretty close to a big blind amount of $3.
As a professional, you'll want at least 40 buyins, so you'd need a bankroll of at least $12,000.
The numbers obviously change if you change the variables.
