Stake for 1€ BB 6M SNG

Hello,

I play on Pokerstars EU.
I'm looking for a stake to play 1€ BB 6MAX MTT SNGs for 8h+ per day for a period of 2 months.
This is my result on 0.25€ BB 6MAX MTT SNGs mixed with some 0.25€ SPIN&GO (not mucch, I'd say maybe 200 or 300?) and other standard and fast 0.25€ & 0.10€ MTT + freerolls.

I can of course give more detailed informations on request.
Thank you.
