A lot of people think... "If I do this"... or..."If I do that"... then success will happen.
That just isn't true.
It is not "what" you do that matters. Instead, it is "how you do it" and "how well you do it."
For your project, doing the job well requires more than "excellent writing". You need valuable information, presented clearly, for a specific audience. For that you need a person who is first knowledgeable about a topic and then a person who is an excellent writer. Those might be one person or two persons or an entire committee.
Then the document that was created needs to be seen by the linkeratti. Linkeratti are people who will be excited enough about your document that they will link to it. The linkeratti might be might be visitors to your website and consumers of the information on your document. Or, they might be a different group of individuals. They might be people who curate helpful information about your industry, or people who who advocate for your potential clients, or publishers who have an audience of people who might appreciate your article and have ways of spreading the word about it.
Start by knowing where your links might come from and develop a plan of reaching those people. Then create an article that will resonate with them and that they will be excited about sharing. The article must then be on a website that these people will be excited about linking to, not on a sleepy website or a crappy little blog. The don't want to send their visitors to such places.
The ideal case is to have the links go straight to your website. If you want that to happen, then get started now to make your website a place that these people will be happy to recommend to their visitors, because they are not going to link there unless it is awesome.
So, make your website a 10x place that is full of excellent, valuable and helpful information that people interested in the products or services that you provide can find troves of information. When you have that, you will not need to try to engineer links. They will come to you, given by your own audience.
One article probably isn't going to be magical, because the linkeratti are not going to link to one kernel in a pile of crap. They will link to you when you have a website full of awesome resources. Build that and your worries are over. So, instead of spending a lot of money on articles that you are going to spread across the web like free popcorn. Plan the library of 10x resources that will make your website the place to go for your potential clients.
This isn't going to happen in a month or probably not even in a year or two. But you have been working on your website for a long time. If you think you are going to be in this business for a few years, get to work on making your website the information hub for your industry.
