Hol Hamoed makeup

My wife is a beginner makeup artist. Someone contacted her following her ad and asked if she could do her makeup on October 1, 2023. My wife agreed, it was late enough, but when she checked the calendar for the Hebrew date, she discovered that it was on the Hol HaMoed Sukkot holiday.

Since it is forbidden to get married on Chol HaMoed, the following questions are asked:

1) Is it permissible to cremate someone for her wedding on Chol HaMoed? (Obviously, it is a matter of loss, but it is the matter of loss that is prohibited)

2) Is it permissible to cremate women in preparation for a halakhically invalid wedding? (Jew with a Gentile or Jew with a Jew [or Gentile, haha])

Thank you and sorry.
