At what point is it time to consider outsourcing Facebook ad management?

Here are my concerns:

Is my budget too low to work with? I’m currently at $80 a day but haven’t gone higher than $120 at any given time. This is mostly based off the volume of sales my ads pull in. If they were to generate more sales, I could quickly raise the budget but for now it’s quite low.

How can I avoid hiring the wrong person? If I’m already using certain data that’s working (LLAs, audiences, etc.) will they be added to FB account and start with what I have - or do they typically insist on only using their own methods? I’ve heard people say you should not expect to be able to view their dashboard/setup - but what if my current results are beating theirs?

What should I expect to pay, and how soon should I expect results if I’m already able to generate some sales on my own?

I would greatly appreciate any advise on this matter. It’s essential that I get sales moving again while avoiding those types that hype themselves up and don’t deliver. I had a terrible experience with a “marketing agency” last year that cost me $13k, so I’m very wary of trusting another marketer. At the same time I need to get my ads producing results again or I’ll go under in a matter of months.

Thank you for taking the time to read this!

If the ads were working but stoped it could have to do with covid but I got no idea what your selling so who knows

About hiring someone to run your ads they probably won’t do any better than you and every time I look into some company it’s always some shady scams I’m sure there are good ones out there but they probably want too much $$$
