My 2 cents here..
Stock HBG, RES in spring, let them get off a good spawn if stocked early enough they will spawn at 3-4", OR... stock 3-4" and they will for sure spawn then add smb and hsb in fall. IF 1-2" HBG and RES are all that's available I believe I would be inclined to give them a year and stock HSB and SMB late the next summer/early fall.
For .5 ac., I'd go 200-250 HBG, 100-150 RES. 30-35 SMB and 10-15 HSB.
I would highly recommend you stock 2-3lbs of crawdads too.. Your SMB will have a hard time making a good living on HBG and RES.
