> I can see the need for hiring at some point but I don't even know where to start.
I have advice for this. Most attorneys, at least in my area, will sit down and talk with you at no charge. My advice is to take advantage of this before you have an actual issue that needs attention and talk with a few of them. Investigate them, talk to their clients if you can, ask about them with professional organizations, etc.
And then just use them for routine stuff every so often. Run contracts by them before you sign, etc. The idea is that you want to develop a relationship with them so that you and they know each other. Then, if something comes up where you really need an attorney, yours is already very familiar with you and what you're doing.

There is a concept of keeping an attorney "on retainer" -- which basically means prepaying for legal services. At a small scale, this isn't worth doing. Treat your attorney like your auto mechanic: keep a relationship going, go to them for your oil changes and other routine stuff, and pay by the hour. Then when you need important work done, they're primed and ready.
