I was more or less wedded to a previous name choice for my startup but I couldn't secure the name or even a good variation of the name so I started thinking of a new name. I ended up with something way cooler that conveys my mission even better than the previous name. I'd never go outside of a .com for my business domain. I think your best bet is to look for a new name. Really, you're only setting yourself up for issues with telling people your domain name/having people try to figure out how to type it in if you go with some country's TLD for your domain. Not to mention you're at the mercy of that country's policies. They could change their policies at any time and snatch your domain if they wish. Don't do that to yourself.
