new user needs help with solenoid driver

Hi All looking for some hardware help with 12v solenoid pwm driver. I need to drive some 12v 2amp solenoids,some are 2 wire so low side driver ok, but some are 1 wire (common ground) and i need some help with a suitable high side driver circuit. need pwm at freq between 61hz & 490hz. not really sure about component selection & circuit.

regards Adrian
