SMD soldering is not difficult at all, when you have a proper PCB footprint. All you need is good magnifier. You will be amazed with how good your hands are under magnifier or low-power microscope. Instead of making one big PCB for four drivers, make four pieces. Order 5-6 PCBs, there are almost no price differences. You have something to practice. If you are still not confident with SMD soldering, send them to me as long as you are in US. I'll reflow them for free.
