Yes, this is definitely advantageous. I own a boutique marketing and public relations firm, and I have frequently partnered with firms that have complementary capabilities that I do not possess. For example, I've worked with advertising firms and graphic design agencies that need expertise in media relations, writing, editing, event management, etc.

You can find agencies with which to partner in two ways. One is networking (including LinkedIn), which is invaluable in this case. Secondly, you could try a freelancer website such as Upwork.

If you would like to discuss any details or are interested in seeing if our companies would complement on another, please feel free to message me.

Best of luck!
