Freelancing involves individuals selling their skills, time, or ideas online through a freelancing company. These companies connect buyers and sellers by gathering them in one place. They ensure jobs are completed and payments are received safely. To get started, one creates an account, searches for jobs, and bids on projects. Challenges include competition and lack of experience, so building an online portfolio and negotiating prices are important. Buyers review bids and select freelancers based on cost, timeline, and work history. Completing jobs on time leads to good ratings and repeat customers, while missing deadlines risks losing money and reputation.
