That's a very nice and diverse Rebel garrison, indeed! 21 figures and one vehicle customized over one weekend is top performance from my perspective.
Like ghostskull18 I really like this Super Battle Droid - Droideka - Grievous - Fusion! Seeing the firing missle play feature of the Destroyer as Flamethrower is brilliant! Never thought of that! Also the SBD torso on Destroyer Droid tipod with alternate cannon looks very cool!
My personal favourites of this lot are the Devaronian with red cape along with the CIS Flamethrower Droid - the paint job on that one is just awesome!
And as (SID) said, eBay is the perfect source for you - especially when you live in the U.S.! Just be patient! You'll find excellent lots of loose figures, vehicles, parts and other fodder on there for reasonable prices or even very cheap. Keep your hobby, work hard for school and later on when you earn money, there won't be any better conditions for you as Star Wars fan and customizer on this planet.
And like I-am-Boba-Fett and Starchaser, I also enjoy following your thread. And I'm sure hemble will also continue following your thread as time allows to. You impress all these great customers on here and that means something.
Keep up the great work, enjoy the hobby, but try not to hustle. I know it can be frustrating to not have time, money or space to instantly realize your ideas, but I made the experience that projects turn out even better the longer they had stayed in my mind before. I started to write down all my ideas, drawn concepts and drafts and collect them in one folder. I keep forgetting stuff you know...
