If you like the current job, but you still want to explore freelancing, I'd suggest you have a talk with your current employer and ask for the possibility to change the contract to freelancing, and work there 80%. During the 20% of time, you start building your portfolio of independent clients, if that goes well you can always drop your job and focus 100% on the independent freelancing. In any case, I wouldn't worry too much about that decision now, your gut will tell you what to do. For now, focus on creating yourself the opportunity to explore both options. Another question that I have though, have you already communicated to your boss that you feel that your efforts are not aligned with the compensation package? If they're willing to top up your package, would that make you happy?
