Not knowing what your business is, those are probably minor things you don't need a co-founder for. Just get an accountant/bookeeper on the financial side, you'll need on anyhow. Do some online reading about cookies and GDPR if you have concerns there and don't stress about it - nobodies going to hunt you down if you're very small fish. If you have serious money coming in you can have a more serious look into it - those issues are not fundamental.
If you need to hire people, open an office, write up contracts, deal with immigration lawyers, deal with tricky shareholder stuff, manage customer accounts ... then maybe you need someone to help.
Ops isn't a problem until you're successful, the taxman won't come after you if you have 10k in revenue, customers won't complain if you haven't sold things to them. It really isn't something to worry about now, at all. Get stressed over not getting any sales, that's what should be freaking you out.
Marketing/Selling, and building the right thing ... this is the hard part.
If you can do the later, most of the ops becomes ... just ops. It's just work. It can be done.
