If you don't mind permanently dying your hair, try Hi-Octane Orange, which I believe can be found at Hot Topic and other hair specialist places. If not, you'll probably have to make do with neon orange (which I personally think is rather ugh) hair sprays. If you're going for the temp spray, gel it, use the holding/molding type of hair spray for a better hold, then color it.
Wig, look/ask around, I'm not too good with wig designs and such
like Solaria said, patience. Try also searching the forums a bit too. Ichigo is done alot (maybe too much?), people have probably already asked this. Search google, etc.
