My question involves criminal law for the state of: Louisiana

I was trying to take two tvs ($700 total) when the guy at the door stopped me and asked me for my reciept, I told him I was waiting on my friend to come who was at the register, I turned around and went and put the tvs back I walked out the door and got stopped by the police and arrested. Should I get a lawyer and what is the punishment for attempted larceny?
