5E Official pre-gen characters


I run a lot of introductory games for friends and acquaintences who have never played DnD and want to dip their toes in. To make things easy, I usually print out 6 characters and let the players choose what they want, and explain it after.

I make these characters myself, but recently found the pre-made Starter Set Characters (for Lost Mines of Phandelver, I think). I really like the second page, giving a little background, name recommendations, and leveling up.

I guess I have two questions:
Are there more of these out there, or only for Phandelver?
Has anyone made an editable version of these sheets (specifically the 2nd page) so I might make my own sets and include spells?

Note: I have form-fillable sheets, but find them either too big or too small, particularly for first level characters.
