Minolta lens profiles for LR

Guys - just starting to learn Lightroom with the hope of building up enough courage to shoot RAW.

I'm seeing there's not much in the way of Sony/Minolta lens profiles for the lens correction - I know you can create you're own, but I'm certainly not there in terms of confidence/ability - is there a source of LR compatible Minolta/Sony lens profiles I can install?

thanks,
Matt
