Music Calendar Website that collects data from multiple sites

I'm in need of an experienced web developer to create a music calendar website for me. This would be centralized website for users to view an extensive concert agenda from multiple venues, to promote live jazz music in the netherlands.

The successful candidate will include the following features:

- Concert dates
- Venue names
- Artist names
- Photos
- Concert descriptions
- Pricing information
- and a direct link to the venue website

Im particularly interested to learn whether it is possible to scrape the data from websites such as
- www.bimhuis.nl,
- www.paradoxtilburg.nl,
- www.tivolivredenburg.nl, -
www.lantarenvenster.nl).
Perhaps there is a rss available that can be used?

I also need there to be an option to manually add events and locations.

There is no strict deadline for the completion of this project. I'm much more interested in finding a developer with the right skills and experiences who can build this website to a high standard. It is important to get to know a developer to start discussions on how to approach this project.

A ballpark figure on what it would cost would be nice.
