Need help on schedule/calendar project!

Hi!

I need some help on a project!! ($)

I'm to set up an application that displays different projects over time. Se picture here: http://andremyr.com/div/prosjekter/stav08/monthly.png

There can (obviously) be more than one project at the same time and I need to set it up for different views, like showing projects in one year/month/week/day.. The user must also be able to select projects at a particular location and type. All this info is in a database provided by my client. They have already built the components to sort this..
The user makes his selections at the bottom area.

My first question is what should I use? I have worked some with Flash Remoting, but still a newbie. But is Flex an option? Any pointers here? The client uses Coldfusion MX and different CFC's/webservices has been set up..

This is in the same ballgame of what I am trying to do:

$$ 800 USD $$ If anyone has any experience to pass over to get this through, I'd be happy to work together with someone on this one... Just contact me and we'll work out the details..

Any help is appreciated!!
Regards..
