As for PCB, I don't, no I DO NOT recomend you use my, also its better for you in the end if you make your own, really just take time

OK I read you had problems with you pcb. WHY? The traces ware too long?

This is maybe noob question but I'll ask it. This is only the driving circuit right? Now I need separate PCB with powerful output transistors right?

well there are some smart thing one should do when switching high currents and two of them are short high current paths, and 2nd is ground plane, which I didn't then think about

I think you didn't see my edited post so I'll ask this noob question again.
Is this only the driver? Do I need to connect power transistors at the output of this PWM?
Ca you show me how you do that? Thanks.
