Flex skinning and modifying

Theres a flex app that i've developed. As it stands, it does exactly what I want. I'm horrible at skinning things however. We will supply the graphics we want on it, though most of it is simple CSS styling. For the most part, it's up to you to decide what styles you want to apply, though it should look nice and consistent. We also need a better preloader then the default Flex one. Again, it should fit the style of the CSS. Transitions will also need to be added, as there's none right now. Nothing extremely fancy, just a fade in and fade out during state changes. Right now there's questions that are answered in a certain amount of time. if possible i'd like an image of something like a stopwatch that counts down. Possibly a Flash animation, maybe a gif? As these are just small and simple fixes, the budget for this is low.
