Necronopticous is correct, you will always suffer much quality loss when you upsize it that much. Your best bet is to get a better picture to start with.

However, since you might want the choice anyway, here's my best attempt (well, my best 10-minute attempt) at getting it to your wanted resolution. Again, I've attempted to hide the loss of quality, but it's still there, and pretty obviously. You're still better off taking a better resolution to begin with.
