Hi Billy. Welcome to Cloud City Garrison. The TK stormtrooper armor will be from 650. on up. Most folks starting out will go to FX Armor. Before you go to E bay . WAIT. Your questions will be answered. You will be directed thru a Private message on where to go to purchase. You mentioned your a big guy. There are costumes that can be worn by a husky person. TK Stormtrooper is not for everyone. You have Imperial officers, Tie pilots, Imperial guards, Look thru the Star Wars Universe for something that may Suit you . To join the 501st is an awesome experience. This is all for charity, and volunteer. The amount of Troops are up to you and how much you want to travel to each event. Also Age is important. You have to be 18 and over to Troop with group in costume. Make sure you read the rules of conduct. If you are under 18 . You can still help as a Spotter. A spotter helps with crowd control and make sure Troopers are looked after, alos take pictures for group. Be a Positive, and a good example to the public. No offensive language, or negative attitude. We are here to have fun and bring Joy to community thru Star Wars. looking forward to seeing you more on forums as you get to know the group.
Peace, Allan
