EU founders: I am thinking if we should hire a law firm or not, what do you think?

Hi everyone, We are two individuals currently building a product. While we consider ourselves co-founders, we don’t officially have a founders’ agreement in place yet. Additionally, we haven’t registered the business yet. My partner is based in Dublin, and I’m based in Portugal. We've decided to register the business in Dublin for tax and other reasons. We’re also planning to start raising a pre-seed round soon and complete in Q1 2025, using SAFE notes and angel investments. I wanted to ask: for things like a founders' agreement, business registration, and fundraising (SAFE agreements, terms, negotiations, cap table, etc.), should we hire a law firm with experience in startups, or is it feasible to handle these ourselves and avoid the fees?
