I'm on the program committee for an author convention in Boston. I need someone who can help us revamp the signup software A Lot. This is your basic event management system, tracking users, panels, tracks, and so forth, with two significant exceptions:
1) No money is processed through it. eCommerce is not required at all.
2) When an admin schedules panels, they need to see recommendations made by the software based on panelist input. For example, "I want to watch this panel (so don't put me on it)", or "I don't want to work with that panelist".
An existing open source project can be utilised for this. We're not trying to exclusively own software, nor are we requiring that this get coded from the ground up. I'm smart with testing and minor scripting, but I don't have the mindset for a project of this scope, which is why I'm ISO quotes.
The budget is rather low, given that this is a nonprofit convention.
Ideally, the site would be coded in PHP or very similar, so that I can tinker with it later. (I realise people have issues with it, but I need to be able to change things later without always requiring help.) However, if there's a language that you can use that's better than this and that can be run on the server, I'm not averse to dealing with it
