Should I even attempt this on my own?

Recently, my PS5 dualsense controller has begun succumbing to stick drift, making gaming increasingly aggravating. As I have already replaced the entire controller once before, I would prefer to not do that again and instead would like to attempt to replace the joysticks myself, preferably with TMR magnetic sticks to dissuade further drift in the future. However, I have no experience with or equipment for soldering, which is clearly a necessary skill to successfully replace these components. So my question becomes this: Should I even attempt to undertake this before finding some way to practice soldering independently beforehand, or should I instead try to find a local shop to perform the repair for me?

As a follow-up, since I intend to begin getting into soldering myself either way for future repairs, is there a good beginner/budget-friendly option for a soldering set? While I am sure the official Ifixit soldering set is of good quality, it is also more expensive to purchase the iron alone than it would be to simply buy a new PS5 controller. While I acknowledge that this would be an investment only made once to grant me access to a much wider range of repairs in the future, it does still somewhat defeat the goal of saving money by repairing over replacing, which is perhaps the most important factor in the current financial climate.
