olivia4 - If you're looking for freelancers for short-term work in the range of a few hours to few days, it's been well documented that platforms like Upwork and Fiverr afford you a lot of potential candidates to choose from. The freelancers that you find on these websites bid on the job that you post. This means you need to put in a lot of effort in screening candidates individually and shortlisting potential ‘good fits’ from hundreds of candidates.
