Help writing some articles and producing a professional document

Description

I need two articles written about financial services markets (maybe more if this goes well), and produced into professional document. Something like the attached document which we produced last year in house but no longer have access to someone who can produce this.
Ideally I'd like someone to ask some questions to help produce a report, (I can share some statistics), and write a summary report and produce a final document.
Preferably keen to build a longer term relationship as likely to have future / ongoing needs.
