If you make great content but don't have the time to edit, Tweakly Video Editing Services is a great place to start. Contact us via Email for both free and cheap professional editing services.
After your video is edited, a low-quality 480p preview version will be sent to you via a Google Drive link, so you can choose to make changes before the final copy is rendered. Rendered videos can go up to 4K at 60fps, and are also shared via Google Drive.
If you're just starting out you could go for free editing, but if you are already established as a YouTuber and have enough to pay for editing services we recommend paid editing services!
More information is available on the FAQ section of either the Free Editing or Paid Editing page.
