how long do you think this would take?

okay well my truck is ALMOST done and ready to drive after i just backhalfed it and 4 linked it but since its winter now im seriously considering just going ahead and making the rest (from back cab, forward) of the frame and stock floor the truck. the frame part i dont think would be a problem im more concerned with body drop part, how long do you guys think this would take me to do? also, what would be the best way to do the front suspension?
