Since you're not to far along in your skating, it's probably better to try and see if you can figure it out without profiling first before you start dropping money on profiles. 8 months is not that long to be skating.
For what it's worth, I have issues with getting up on my toes too much. For me, it's a combination of bad habits and small feet. I'm a size 4.5 and I'm a full grown adult. It took me like 2 years of gradual tweaks to find my way to my current profile, a 13/26 with a -1 pitch. Very few people use negative pitches. During practise I generally don't have issues. I can use a standard profile and be fine doing things, but during the course of a game, at game speed and when I get tired, the 40+ years of bad habits rear their ugly head, and I can end up on my toes too much. The negative pitch helps settle me down, so I can get a full proper stride instead of choppy ones.
Again, in this instance, it's probably better to work on yourself a bit more before you jump into the deep end. And IMHO, it's probably better to do a bunch of incremental changes rather than jump head long into something like a quad profile. The quad changes a bunch of variables at once, and if it doesn't work, it's tougher to figure out what your next move is, but if you only change one thing, it's easier to diagnose if its a positive change or not. Yes it can end up being expensive, but it's a sure and steady path narrowing in on what's right for you rather than one where you're taking a bunch random shots in the dark hopping to hit a bullseye.
