This will build you some solid but very basic ranges to begin with.
Use combonator.
https://combonator.com/
Plug your RFI ranges in the combonator
App by position UTG,MP,CO,BTN,SB separately then build a defense range of 35% from each position 65% folds.
so
UTG for a 12% range plugged into combonator
55+,ATs+,KTs+,QTs+,JTs,T9s,98s,AJo+,KQo
gives me a defense range of 35%
call
QQ-TT,AKs,AKo
4bet value
KK+
4bet
bluff
AQs-AJs
To work out that value to bluff ratio on 4bets just divide your value combos by 1.5. So KK+ is 12 value combos 12/1.5=8 so 8 bluff combos.If you 4bet for value with QQ+AK from later positions.Then that's 34 value combos 34/1.5=22 so 22 bluff combos.So for QQ+ AK your 4bet bluffs might look something like A5s-A2s,KTs,QTs
3bet ranges get more complicated id suggest to begin with 3bet mostly for value and just add some bluffs like suited Ax maybe some Kx Qx like A9s-A2s,KTs-K9s,QTs-Q9s and even a few suited connectors vs most positions.But vs utg and mp you can get away with just 3betting KK+,A5s-A2s or even QQ+,AKs,A5s-A2s,AKo
