The first thought that crosses my mind would be something like Discord, where you can have voice chats with anyone, for free. The most feasible medium to get ideas through the internet though would be video, you said you can't record and have the audio drivers working at the same time? That's a shame because I don't see people getting a "hand-on" experience through just voice... maybe Google hangouts where you can have video chat?

If you want a laptop your options are limited, but if want to build your own PC then I highly recommend the PCMR Build list it includes some of the best builds, although a little outdated, by one generation. You can always ask in the subreddit or /r/buildapc or even ask me! I'm willing to help!
