I've used Premiere Pro professionally for 6 years. The Ultimate Editing Pack contains everything I use.
All presets and project files can only be used in Adobe Premiere Pro.
Other assets can be used in any program, but I'd always recommend Premiere!
You can pay via Stripe as of now (including Apple and Google Pay).
PayPal will be supported soon, but in the meantime send me a Twitter or Discord DM and we can sort out payment manually!
The Ultimate Pack is designed for all skill levels, as long as you know how to use presets! There's information on the owners' section of the site on how to use each part of the pack as well.
