Enalais, sorry for the wait. Here's your choice of starter ships.

If you choose this, you will still have a large cargo bay but have 5 average sized prison cells, 1 individual per cell is recommended though, you know xD
Also a Stealth device like the DFT put on the Crescent Class Freighter

(Follow [url=http://img2.wikia.nocookie.net/__cb20090601153758/starwars/images/7/73/YX-1980_space_transport.jpg]this[/url] to follow where things are)
If you choose this, the lower most 4's on the Layout will be converted to prison cells, 4 cells for each lower most 4 (That's 8 cells). Two Starfighters from DFT (Depending on your choice) in the middle most 4's (Cargo bays can open and act like a hangar, just no oxygen until closed and refilled). The uppermost 4's for Cargo. The Fighter option is an option, you could have 1 fighter or no fighters.

If you choose this, you gain 10 prison cells

They all have their advantages and disadvantages. YU-410 can take on cruisers and fighters, XS-800 can only take on Uglies, and the YX-1980 can do decent against Fighters and Craft a little larger.

Edit: Enalais, I'm going to let you have this schematic along with the others and also two already built for your little fleets whever you want them to go
