Like many have said before if you are really wanting to get started then start out by going to a local REIA meeting and talking to people from the groups. Wholesaling may sound simple but you will be whacked with the reality stick quick when you find out that it takes a lot of marketing and time to call back home owners, drive neighborhoods, send out letters, put out signs, etc. Its a great way to get started and learn the REI business so you can grow from there if that's what you are looking for. But if you are looking for something part-time then look at being a bird dog for a wholesaler or investor, you'll make less per deal but it will allow you to learn from that investor you are working for.
One thing that I am a true believer in is giving to the community. Go to your REIA or meetups and see where others may be lacking in their business then see how you can fill that gap. By offering your help to others it shows that you are serious but it also lets them know who you are and in exchange they will (for the most part) offer to help you too. We all have talents in certain places, even though we are talking real estate your talents in other places can help as well.
Good luck
