Have the bearings removed and throw them away. At this point with all the hammering and repressing they are probably damaged and will be side loaded when you put the wheel back on.
Then get some brand new QUALITY bearings like SKF or NACHI (or any other quality made in JAPAN brand), instead of those cheap low quality CHINESE made All Balls bearings. You can purchase high quality bearings for around $10 each, which end up being about the cost of the All Balls kits (you can also buy the same bearings All Balls uses in their kits seperately for about $2 each if you do want to go the cheap route).
Then have the bearings either installed by a different reputable shop or purchase the proper tools (a bearing driver) and do it yourself. Heat the hub with a heat gun and freeze the bearings before installation and they will go in easy. Make sure everything is cleaned properly, including the hub and axle. Also make sure you grease the axle a bit before installing it. Autozone rents tools and they have a blind hole bearing puller which works great for removing the bearings and also a bearing driver for the install.
You mention "This project is getting frustrating, it seems like nothing ever works." Having the right tools, quality parts, and patience makes it a lot easier. I have learned that the hard way many times over the years.
There are certain parts of a motorcycle you DO NOT go cheap on: Wheel bearings, brakes, suspension, and tires. Buy the best tools and parts and it will save you money, aggravation, and possibly your life.
