1 song string orchestra

I have an arrangement for a song that needs some real string orchestra. I have recorded string-quartet before, but am looking for something that sound a bit more lush and expensive for this arrangement. I'll attach an mp3 of the song below, in it there is two parts that needs the string-orchestra: 1. The melody that can be heard 1:24 - 1:29 2. The kind of crazy part that is played 1:43 2:10 in the song. Thanks
