Seems like some of it this is due to time (not being able to take a class, or to do prints for clients, custom galleries, etc.). Can't help but think maybe working on skills more before getting into this as a business would have been beneficial so maybe figuring out what /how much in the way of client work would be manageable for now and build from there.
I agree with other comments that many of your photos are nicely done, some are quite lovely, but with others I see some need for improvement with exposure or editing, framing and watching for distractions, etc. I think it takes practice to get good at photography and I don't know if you can get to a better professional quality/skill level learning online only.
If online learning works best, then see if there are any opportunities along with that to connect with other working photographers in your area to get advice, toss around ideas, etc. Maybe watch for one-day workshops. Or photography events at community art centers, or photography related exhibits, etc. (Are there any Foto Focus events in October in your area?)
