There are some sites with ACR re-skins that may have better uptime.
I think your best option would be a mixed strategy of low buy-in ($1-$2) sit and go/double or nothing where you essentially have to finish in the top 30-50% of a mini-tournament to cash. Your likelihood is far greater in a field of 8 to 10 than in a freeroll with a field of hundreds, or even thousands sometimes.
A good starting point is this thread:

You can supplement this with low buy-in MTTs and some freerolls until you see which approach brings more consistent results.
Personally, I would avoid cash games like the plague but that's just based on my personal experience. Some people are profitable at cash games and have built up large bankrolls. The benefit of cash games is that you can gather data on regulars and build up HUD stats whereas in tournaments you may not often see the same faces.
