First of all I would master your standing and running with a hurdle cartwheel with both hands and one hand. Then attempt doing a dive cartwheel, then with one hand. You really need a lot of momentum. I would practice swinging your arms and keeping your hands up for longer and longer. Then one day you are just going to try it and you will land it! You really should stretch before attempting this trick and you should have a supervisor or a mat or even grass. For technique swing your arms in a circular motion and when you jump off to do your aerial you keep all of your weight on one leg and you really flick that back leg. Remember you won't get this trick over night it took me about 2 months to master mine. But I don't know your strength in tumbling or acrobatics. So that's really up to you and your skills to determine when you will master the trick. Also I wouldn't classify them as professional they are more harder but they aren't all that hard.

Defiantly learn how to do an ordinary walk over first before you even attempt a front aerial! Side aerials are not hard. You need to practise running up and doing a cartwheel and taking your hands off at the last second, or running up and seeing how long you can keep them off for. You've got to really push off your supporting leg to get around too! It just takes practise,youtube have a lot of demos and maybe some acro classes might help :)

side aerials are easier and I would try for that one first wat you have to do is practice differents things like hickups and pickups. Hickups is a delayed cartwheel while pickups you take your hands off the ground before you come up. Also try these running and diving into them. Once you feel comfortable try imitating the movments so run about 5 steps plea and jump off the ground that is the prep for it. Finally try adding the aerial to that movement. Good luck hope I helped!
