You can easily reach out to our support team right here, in the same way as you've opened this thread. Our team is available 24/7 so feel free to post as many questions as you have, and our team will certainly guide you.
Regarding documentation, you can access that here. We are currently in the process of a major overhaul of this, but this should certainly get you started and past the feelings of overwhelm.
Hopefully that gives you a good starting point. The design you mentioned is definitely achievable and once you've taken a look through the documentation, you should feel more confident in taking that on. Like I say, our team stand by for any questions you have to help you achieve the desired look.
