There option to do translations but it's more risky specially in this project, but still worth mention i guess.... do it Minecraft style there something called: http://crowdin.net/ ...which provided crowd-sourced translation service, where people gather and translate together, suggest translations for each string and to verify qulity it being voted. Minecraft for example using it and thats why it been translated to so many languages in short period of time. Ofcorse downside is there no 100% gurantty that translation will be 100% correct (specially on niche languages, even popular Minecraft with just 1000 strings have problem with that, i contribute to Polish translation and i didn't seen more then 20 votes for a string) and monthly cost (135$ for 50000 strings, there possibility of unlimited but requres negotion)
