I will build a homebrew anything on dnd beyond

Yes and no. Technically speaking you need to have at least a Hero level subscription in order to utilize public homebrew, but if you do not have one there are still options for you to still be able to use it. We can discuss those options together if this is an issue for you.

There is a package addition you can select for me to do so, but the standard packages don't come with them by default.

This gig is specifically for homebrewing for D&D Beyond, and having integration within it's system. D&D Beyond does not support class homebrew, only subclass homebrew. If you wanted a homebrew class, you would not be able to use D&D Beyond. If this is something you still want, message me directly.

No, I can generate a custom offer so it's all in one place. Message me before submitting your request and I'll generate an offer for you (at a discount for bulk ordering).

There are a few restrictions that dndbeyond doesn't have any integration on. The most common restriction being you cannot change the base damage on weapons. You also can't change AC calculation beyond a generic increase/decrease etc. There are also limitations to spells. Just ask and I can find out.

In order for the homebrew to be public, it can only use Basic Rules content. This is really only a restriction for access to specific spells. If you are dead set on using non basic rules spells, it would need to be a private homebrew which makes the process harder but not impossible. We can discuss.

Potentially. Message me before submitting a request.
