I just got a painter's pole and combined it with my blimp using a male 3/8" flare to female 1/2" pipe fitting adaptor. The 3/8" flare end goes into standard microphone fittings, so can be used with anything you would normally put a microphone on. I disassembled a mike holder I had to create my blimp, so this worked really well. The painters pole is 16ft for $15 and the blimp was < $10. Decent Mike and a wireless transmitter makes a really nice location setup with no cables.
The microphone blimp is constructed from:
plastic or metal (metal lets you bend over the sharp edges) gutter screen (for keeping leaves out of gutters - $1.50 home depot - way more than you'll need)
2 equal lengths wired or zip tied together to make a tube
cut little triangles out around the nose end to round it slightly
rubber bands shot through and held on the outside with chopstix ( - | - | alternating directions on the rubber bands to slide the shotgun mike through)
Cover with costume fur sock (some sewing required) for wind diffusion
attach (I used wire) to a mike holder base (they're cheap at radio shack)
3/8" male flare to 1/2" female pipe adaptor ($1.50 Home depot) forced onto
16' extendable boom pole ($15 Home depot) The aluminum is light and can hold my 8 lb cat up off the ground (they loved when I was testing it).
The rest is just electronics, decent shotgun mic and wireless if you choose (or a really long cable strapped to the pole to eliminate cable noise).
Here are the pix (I've since switched the mic stand for a much lighter and longer painter's pole):
