Geofencing Monitoring

Hello

We are looking for a basic geo fencing script. For example using google maps, we can select a area, lets imagine seattle. Upon this it will show public posts from twitter, facebook, flickr, imgr, youtube that can detect from being within this area and which can be filtered by date / username,

This is not for a commercial site but for our requirements within our small business. We have looked at those businesses which offer such a service but these are not financially viable for us.

Can anyone recommend such a script? We are happy to discuss costs for creating such a script also.

Thanks
