you are better off hiring someone to shoot for you. As for HD - what HD?
HDV - if so, don't bother. DVCPROHD? - perhaps you should buy a HVX200
for $10,0000 and pay someone on a deferred basis to shoot for you.
HDCAM/HDCAM SR? - This might be a great deal to gather very high
quality footage for a reel to raise money.
DV - the story had better be so damn good the market won't care 3-8
years from now that you shot it on a dead 4:3 tape format in a world
gone 4K high def in 16:9.
