How do I draft operating agreements and client contracts for a small agency?

[EmmaS]

I'm in the process of formalizing a partnership for my small digital marketing agency, and while we have a handshake agreement, I know we need a solid operating agreement and client contract templates. I've been reading about contract law for small businesses, but the legalese is overwhelming, and I'm terrified of missing a crucial clause that could leave us exposed to liability or partnership disputes down the line. For other small business owners, how did you approach creating your foundational contracts without the budget for a full-service lawyer from day one? Did you use a reputable online template service as a starting point and then have a lawyer review, or were you able to find sufficiently clear resources to draft basic but effective agreements yourselves? What are the non-negotiable clauses you learned you absolutely needed, especially regarding intellectual property ownership, dispute resolution, and termination conditions?
