I am fed up with the constant bullshit that goes hand in hand with being an employee and am thinking about going freelance. I usually have a job or two on the side, so I am used to dealing with clients.
I am 30 now and have been developing professionally for nearly 10 years. I am experienced in PHP, Python, Javascript and a load of other things. I know I have the skills needed to make this happen.
The only thing that holds me back is the fear of being able to pull in a steady stream of clients.
Ideally I would like to pair up with someone who has a solid idea but needs a tech guy to make it a reality.
Does anyone here have advice? Should I maintain a full time job while building clients on the side, or quit and put myself into a sink or swim situation? Am I making a poor decision by going freelance?
Start trying to build a customer base on the side. Once they're bringing in enough to cover your expenses with a reasonably healthy percentage over that, then consider quitting your regular job.
Freelance work is not steady work, so you have to be sure that you can cover your expenses with regular work before you should be thinking about dropping a regular income for it.
You will need to build up a steady base of regular clients, and build up word of mouth. If you're not a designer, then it becomes really hard for people to discover you in any way other than word of mouth.
tl;dr: Don't quit your day job. Work extra hours until you're earning enough regularly and reliably to cover your expenses, then consider dropping your full-time job.
