[support] Advice on availability-type module(s)

[Peter Horn]

  Hi all,
I'm looking at a "volunteer then chosen" situation. It would work 
something like this:

1. Member signs up, indicating name/location/qualifications, etc. [easy 
- core]
2. An "availability calendar" is set up for a period.
3. Each member can indicate, up to say a month ahead, his availability 
on a day-by-day basis (maybe two types of availability - single day or 
multi-day block).
3.5 Member can edit his availability.
4. When the occasion arises, the "customer" can view the whole calendar 
and accept some members' offers (mark them "used").
5. some statistical views would be nice (e.g. customer can see who has 
been used for how many days this period.) [also easy]

Mapping this to the real world,
member <=> volunteer firefighter (specialist roles)
customer <=> fire service management
occasion <=> fire requiring specialist resources
period <=> fire season (6-8 months)

I'm sure there are one or more modules that either do all this 
out-of-the-box, or could be easily massaged into doing so. I just need 
steering towards it/them. Any suggestions gratefully received. [I've 
poked around a bit, and the availability and reservation modules I've 
seen aren't suitable.]

TIA,
Peter
