There are many searchable job sites, some are free, a few have a monthly fee that allows you to view jobs. Finding telecommute jobs is the hard part.
Most of the job sites offer biding on jobs alongside people from many other countries, and the people posting the jobs are looking for cheap labor, meaning they want quality work but only willing to pay peanuts for it bordering on insulting.
A newbie does not know what to charge, how much work is involved in a specific job to determine what to charge. As someone just starting out, you need to have a minimum amount you are willing to work for because without a rate schedule, what will you charge?
Many of the jobs online require travel, and are in-house. Are you willing to move? Are you willing to work in-house? If you answered yes, realize that some of these jobs are short-term for a project only.
Freelancing means working for yourself and setting your own schedule, and you are responsible for accepting or rejecting a job, the expenses of running a business as an entrepreneur.
Make no mistake, working as a freelancer is a business, and you may need a license, a DBA, LLC, or C status, business insurance, bookkeeping, record keeping, and taxes. If you want to be a full-time freelancer, health and dental insurance is also up to you.
Freelancers should start out with a rate schedule that takes into consideration thinks like, overhead, running the business, rate per hour, rate per project, office equipment, while not charging too much pricing themselves out of jobs.
Working as a freelancer is the hardest work you will ever do.
The best way to find work is to start local building a portfolio (work you can show to prospective clients, thus proving you can do the job). This portfolio should be readily available for clients to look at.
Being a freelancer is hard and may take years to build a steady flow of clients. You have to have a reputation, and brand yourself.
Search for jobs within the type of freelancing niche you want to work in, and be patient. This will cause most people to leave their comfort zone, if you cannot move out of your comfort zone, freelancing is going to be difficult at best.
Search now to find work, but remember not all jobs are the same, and neither is the person posting jobs.
Good luck in your search.
