MOSFET High side switch

I am looking at arduino module that is used for driving high side loads, I will use it to generate a pwm signal from arduino that will be converted to 12 V (High) 0 V Low. I see one solution is to use a pnp mosfet and connect the power supply to arduino vcc. But I don't think that will work in my case since I use common ground for other purposes. Another solution was to use a transistor to drive the p mosfet, I think it is good but I hope if there is a ready module for that purpose.
