Mitigating Development Risks

I am involved in a project at the moment, where we are looking to develop an online application using (for us) a new technology. The company has an outsourced technical team (not first-language English speakers) who will be doing the development, but none of them have experience of this technology.

I've been looking at mitigating the experience risk by getting them trained up, ensuring that they have the tools to practice with the development environment (and budgeting in some time to do so), and making sure that they may have access to some expert resource during development, but I am not entirely happy that the risk is completely under control. Does anyone have any other suggestions for reducing this kind of risk(s)? And, yes, I have looked at the avoiding it all together option!
