Uncertain what term to use for service required

Hi all. I need to hire help but I’m uncertain what the correct term to use when searching for it in the marketplace, or the title to use when asking for it. I need to make a business look like it's existed for years more than it has. “Business” may not strictly be the exact entity; it could be a business, an artist, a product, a person, whatever, it’s all much the same principle, but let’s call it a business for now.

I need the following results:

1: In search engine results, I need the business to show on various active websites, buried 1 to 10 years in the past.

2: I need the same for social media. Perhaps an editing of older posts so the content looks to have been originally dedicated to the business?

3: I need a few websites created, fake brick-and-mortar businesses dedicated to the type of business I’m promoting with the promoted business/product having been showcased in the past, so that if you searched on the website or a search engine, it would result in these older pages.

With that in mind, what am I looking for? What are the terms to use for this service? Or should I be looking for a multitude of services in the marketplace, such as in the SEO links, Social Media, Website Design, Domains and Websites for Sale?

Thanks so much for the help.
