Get ready to spend some cash there Nick. The stuff that you have won't cut it in real tec diving. You'll need areal backplate and wings, not a seaquest bc. You'll also want to get a new drysuit set-up, though you might be able to work with yours to start with.
Fifth Dimension has a great reputation around the country. THe owner actually came to Wisconsin this spring, and will be back this fall, to run some DIR- F classes for a shop that some of my friends own.
You should start by taking their fundamentals class, with the gear that you have now, so that you can see what you will need to buy, and why. It will also give you an idea of what your going to spend in the future.
After taking the class, where you will learn a lot, and pricing everything out, which will add up as you dive deeper, you may just decide that freediving is a better way to challenge yourself in divingm which is what I have decided to do.
Either way, you have a great shop up there to train with and there are also some nice deep wrecks to dive on when you are ready.
