Happy to help. My first question is what makes you think you need to purchase a solver? What is your plan for poker now and future/what stakes you planning on playing now/future? Depending on stakes you plan it play or rise too you may never need to waste money on a solver or any overly expensive 1k course. Below is a link to a solver(best price I could find) that I maybe considering if I feel I need it. You don't need one to beat micro stakes. You may want one if/when you reach 25nl or 50nl(maybe not though idk). There maybe cheaper solvers I haven't noticed/found one and not sure how good GTO+ is maybe someone who owns it can talk to that. For me the price is right if or when I ever need one

As you're new I would recommend a couple courses(links below) at runitonce poker. Peter Clarkes "From the Ground Up Course" is solid and for the price($50usd) it's well worth it. If you wanna checkout Peters coaching style first search Carrot Poker on youtube(link below). Also I haven't purchased this course so won't comment on it yet but Owen Shiels offers "From The Ground Up MTT Edition". That course also is at runitonce poker. It's a bit pricer at $150.00usd but probably still well worth it I would guess.

Hope some of that helps you out and gets you started in the right direction. Good luck at the tables and be sure to have fun.
EDIT: For leaks I recommend Poker Tracker 4(PT4). You'll have to play hands first but once get some hands played PT4 has a good piece of software included called "leak tracker". It will run an analysis and spit out results for you. The more hands you have the better. With a small number of hands though I typically work on things that are way outta the green. The things that are close are likely fixed with a larger sample size of hands or need a large sample size of hands to even show up.
