Are you looking for real or artificial flowers? The link your provided doesn't make that clear.
If you are looking for artificial, try afloral.com
You may also want to try talking with local florists for ideas if you are going to be doing these with real flowers. I wouldn't recommend that you use real flowers as you would be doing the work right before your wedding. Professionals know what they are doing and will guarantee results.
