Come on dude, it's like 5 bucks for the high-res cliparts. Look at all those compression artefacts in the low quality preview - you're not going to be happy with the results. Either you don't need them this badly, in which case forget about it or do it yourself (since you want transparent PNGs you must have at least fundamental editing skills). Or you really want/need them, in which case 5 bucks for good quality should be a no-brainer. No need to scam an artist out of the petty few bucks they make.
Pirating a $500 piece of software - sure, I get it. But this is the same ridiculous shit as pirating a game that regularly sells for 5 bucks on Steam. The additional effort is nowhere near worth the savings. Your request is a job well below minimum wage that will not even come close to the original quality. It makes no sense.
