Since a PR agency can help with branding, SEO, social media presence and direct sales, Bert says that you should hire a PR agency as soon as you can afford it. I agree with Bert on this one. Hiring a PR agency will be like hiring someone to build amazing links through SEO, grow your social media presence, and it will also generate real sales and bring real customers. I myself will hire a PR firm or agency once I am able to afford an extra $10,000 per month because press is amazing for so many other things.

Something you can do is figure out ways to get discounts from a PR agency. If you can get a discount, you can hire them earlier on.
