Good morning, I would like to know what kind of attorney I need to file a claim for a business who wont honor a contract?

I had a party scheduled at a venue in Las Vegas on 10/24/20. My contract states that if I cancel 30 days prior to the event I would be refunded any monies that I had invested. I have been trying to cancel this party since April 23. The owner has been dodging me, telling his staff to say he is not there, and not returning my calls or emails. Finally, on May 11, 2020 I caught up to him at the establishment to ask him why he's been dodging me, not returning calls and not willing to refund my deposit when he was Johnny on the spot as long as I was making payments. He could not give me any answers- just stood there. Then he said... all I can do is give you a check for the amount right now, I said I'm happy to take a check as long as its good. He assured me that it was. It wasn't! It came back from my bank this morning with an additional 35$ fee. I now see the disingenuous and dishonest person I am working with and it certainly looks like I will need legal representation. Please help!
