p-channel high side mosfet help - switching with 3.3v

I also have a requirement to switch 12v to a horn (the horn draws about 5 amps) from a logic 3.3v

I am lost as to what the circuit for a high side load looks like, can anyone make a suggestion I think I need a p-channel mosfet but I dont know which one or what considerations I should cater for? This is a noob type question but I find online many alternatives but I don't know enough to say which I should use. All help and discussion welcome thanks in advance, Gus
