Default Sand Blasting

Got a project coming this week. It will be 20 peices of 7075 10 X 15. [b]They are pretty rough coming from the CNC shop I guess less machine time means rougher finish and less money. Any how, last time I started with 80 grit and worked down to 2000 then polished and they turned out well but it took 3+ hours. I was told sand / media blasting would be alot quicker. Any sugestions?
