I'd recommend checking out a few of the adoption agencies. I know MAW and NGI both have panels for adults that are looking for parents. As far as the kid avi thing and swearing, not all kids are 100% against it. I play a kid avi and an adult avi both in SL, and have the same parents on both, my dad doesn't censor himself when it comes to language but it has never bothered me. So may not want to rule that out completely just based on the swearing, just make sure you list that in your notecard.
