How do I find someone who could sell my product?

You've already received a lot of good ideas and suggestions and I've looked at your website. I suggest you add a "How it works" one minute video. Also I clicked the samples section and I still couldn't get it.

If you are looking for people who would sell your product on a commission basis, that is possible but not easy.

Feel free to get in touch.

Paid traffic from Outbrain, Taboola, Facebook, Google will generate far more profit than hiring someone.

Paid traffic also allows you to scale up forever, instead of hitting the block of hiring more humans, every time you'd like to increase your sales.

Essentially, are you looking for someone to just sell your product?

The first thing that comes to mind is checking out Upwork.com.

What exactly is the site - I checked it out, but couldn't make sense of it off the bat. I even typed up my website and had no results. If you'd like we can talk more about this and see how I can help.

You need a person with two kinds of expertise:
1. Who can run meaningful traffic to your website
2. Who can read user behavior while this meaningful traffic is browsing your website
Let me elaborate, driving traffic to a website is easy in a way but you want potential customer flow and exclusion of random traffic. So, target audience profiling is critical.
Secondly, user behavior will clearly suggest which company is someone is looking at. You want to sell banana to someone who has been checking different bananas in the market.
Someone who keeps a tight marketing cycle, hire them.

There are a couple of strategy and product questions that need to be addressed before considering paths forward for revenue generation. I've only taken a cursory look at your website.
Who are the most common end users and what is their purpose? Does offering packages or bundles make sense? That would be a simple upsell. E.g. One report $99, five reports $350.
Who in organizations are buying these reports? Strictly salespeople?
Is enterprise partnerships a path to pursue? If the target is international salespeople - is salesforce.com a logical partner? Do you have the ability and experience for enterprise level partnership agreements?
What makes sense for you to give up financially per sale? Does paying an internal salesperson on a primarily high commission percentage make sense and is it feasible?
Could you white label this to an Owler type competitor (assuming they are one) or become the horsepower behind a similar product. Don't give away all of your secret sauce but that type of agreement can be a huge step up rather than a salesperson knocking on doors and delivering steady but noticeable and profitable results.
While not necessarily an answer - I hope this outlines considerations and tradeoffs and isn't just telling you SEO techniques.

I would suggest as you are going alot of various industries, that you build individual sales funnels for each topic.

One of the ways that you can do is to write:
Top 3 trends for X industry (as a blog, video) and use it as a sponsored ad and for your audience that engages just retarget them. Of course to access the full report, they need to pay.

Also if you have key influencers as part of the research, you can go ahead and add it there!

There are multiple different angles to answer this question. I will start with a few clarifying questions first.

Who do you currently sell to? (industry, companies, individuals in those companies, etc)
What is your current sales process?
Where do you get traffic from? (digitally, phone, in person, etc)

There are only 3 ways in increase revenues in a company via sales. Get more customers, get them to come back more often, or sell them more things.

If you currently have maxed out your highest revenue channels, you would need to open a new channel, thus a new form of sales professional to step into that role. If you have not yet maxed it out, you would need someone with experience in maximizing that channel. This could mean hiring an industry leading sales person, or maybe a facebook ads expert or agency if that's your core means of sales.

Since you have a broad question, I can't give you a definitive answer but this may help get your head pointed in the right direction.

(quick note on the site, when you click purchase report, it takes you to a login screen. That presumes #1 that any user is already a member (at a min it should be a simple sign up as default not log in) and 2 that is a friction point in sales, the reality is you could capture an account on checkout for those folks that just want to buy a single report. make that as easy and as simple as possible and sales on the main page will increase.
