Dont think that i can do all what i have read with using mssql and all that other stuff just looking for a simple hack that i can use.

There is no such thing as hfs hack. You need a mod to do the hack for server side but im not upload those files because it will ruin any private servers that didn't have hackshield or xigncode enabled on their servers.

If you want to test things out on your own servers just modify your DBs from your servers to make your critical damage high or OP(overpowered) have fun.
