If you want to get great results, it doesn’t take lots of high end gear. Really. If I was your consultant , which I am since you asked. First things first, Room/s, get your recording and mixing rooms lined out, and properly treated ( DIY, or hire pro either is usually better than nothing). If you plan on recording and mixing, spend some money on good detailed monitors, and headphones. If you don’t have a very good room, and a decent way to hear what you’ve done, it’s going to be hard to get a mix that translates well. You don’t have to spend a lot of money now days on interfaces, mics, and preamps to get great recordings.
