I agree with Vlad that contact marketing is going to be your best best.
This is a long-term strategy, but in my 4-year experience doing this for a niche SaaS company, our blogs, guides, and video presentations can often be backed with paid traffic with great and more immediate results. A combination of generating traffic with content and retargeting that traffic with paid ads had worked nicely for us.
As Vlad touched on, you're going to want to target more low-competition but high-value keywords (specific to your service) first, so I would use a tool that helps you discover search volume. I would definitely add "template" or "guide" to your keywords where appropriate. In short, you want to develop content that is 20%+ better than the existing top results for that keyword. If there are no writers on your staff, consider hiring a ghostwriter that will interview your subject matter experts or make sure any SEO provider you hire offers content writing as well.
The key step many people miss is to create a syndication plan for who to promote your work to when it's published so you know your efforts aren't wasted and you can achieve results a lot quicker. Then get other sites to point to your content to increase your rankings. There are some backlinking services that claim to do this for you, but your best bet is to monitor a few media opportunity services (like HARO) to find link-building opportunities. This can be painstaking as you can send 20 pitches and only get mentions from 1, but the more you do it, the better you'll get at pitching yourself. If you're a small team without the budget to hire out for this work, dedicating time to this is going to be your most valuable asset, and creating a schedule will greatly help you. There are a lot of Free resources of inbound and content marketing that will help you on your way, but you need to dedicate time long-term to make it work.
