Hey,
I've been outsourcing most of my projects until recently.
Based on my experience you should'nt try to save a few bucks going with the cheapest bidder ( if your doing it on freelance, Upwork etc), will get you more headaches in the end.
Check the reviews of people that you plan on outsourcing to. Make sure they are'nt doing only small projects, look for the negative feedbacks ( many are actually outsourcing the received projects lol , You don't want that). Check their Portofolio, have a chat with them etc.
And if your doing it via freelancing platforms, don't release the funds( create the milestones and leave them there) until your project is finished you got exactly what you agreed upon.
Once the freelancers are receiving their $, their interest in your project will drop considerately.
Good luck,
ps: without the wall of text:
1. Reviews
2. Quality of Work
3. Price
Doing it like that will end up cheaper in the long run. ( rather than going with the price as you main factor)
One more: Make your project requirements very very clear. Using steps, photos, videos if possible. This will get you better and more accurate bids.
