I agree that the holiday season is a great time to make some quick bucks for yourself.  As a business owner, you could have a holiday seasonal side hustle that you do at that time to as to increase your revenue and stream of income.

If it is not a business that you already do, you should do a needs assessment before venturing into a new one.  Secondly, understanding the business that you're about to start because. Do not jump the needs assessment phase because the business that you think is profitable may not be profitable without understanding it.

In my opinion and summarily, the ingredients are needs assessment, understanding and building the business model, lastly, let people know you for it, so be consistent and you will attract new customers.
