By escrow transactions I mean basic 2 of 3 multi-signature transaction like here https://blockchain.info/wallet/escrow
Are there any other bitocoin clients where I can do this?
Here are a couple options available to you. I am not associated with any of these sites and would recommend you do your research before proceeding with any of them. Providing any said research to other readers would be helpful for the community.
