Here’s an answer to a similar question I posted recently in this community that may help you, but it isn’t specific to what you asked as that is very dependent on a multitude of personal factors (e.g. financial and growth goals, current financial situation, sales abilities, types of clients you’d prefer to attract, etc), but I’ve bolded the pieces that are more relevant to that…
Having freelanced for paid search in multiple capacities over the years, one thing I’ll add here that often gets overlooked by people considering or just starting out freelancing: accept that you are starting a business; own it. Meaning you’ll want to get acclimated to business fundamentals outside your responsibilities related to providing PPC services, such as accounting (e.g. money in, money out, taxation, invoicing), time/project management, communications, empathy, legal, sales, retention, etc.
Clients may initially trust you with their business based on competence, but unless you really know your stuff, create a solid business relationship, and manage your time and finances well, keeping those clients and/or keeping yourself healthy and profitable may present a challenge.
