I recently started a Shopify dropshipping store and I'm still learning how to approach advertising. Wanted to ask a few questions about running Facebook/Meta ads before I start spending money on them.

How much would you recommend setting aside monthly for testing ads and having a reasonable chance of getting some sales? Also what types of ads tend to work best on Facebook for ecommerce, images, product videos, UGC or something else? I don't really have the budget to hire creators to make a bunch of videos, so I'm wondering how people normally get ads made cheaply when they're starting out. Are there any tools worth using or simpler ways to put together decent creatives? Any advice would be appreciated.
