Need 3-4 tracks mixed and mastered for vinyl relase - genre house and techno

Hello my name is Gustavo. Im currently planning to release an EP on vinyl. The genre is deep and pumping techno and house. I draw inspiration from both Chicago and Detroit-styled house and techno. I have pretty much the tracks ready to go but I need help with the mixing and mastering. I've done the mixing myself this far which hasn't been ideal for vinyl. The tracks have not got the warmth and deeps I was going for and turned out playing at low volume. The attached mp3 is samples from all of the tracks .
