Entrepreneur interested in receivables factoring / equipment trust certificates / negative cash flow conversion cycles etc.

Lets say widgets in a certain new niche market are sold by companies that were either constrained by the funding limits the founders themselves [small scale results & pure vision/product& services], or by angel/vc's (leading to dilution of shares + investor pressure; leading up distorted of nearsighted vision/untapped potential).

The problems that i'm seeing seem to be caused by a lack of sophistication when it comes to employing the many financial instruments that i know exist.

Some of the people i respect most, for example Jeff Bezos; (he studied computer science and electrical engineering & after graduation he worked on Wall Street) seem to be hybrids that have mastery of financial systems and technological systems, leading them to be able to accomplish things that no-one else is capable of.

Personally i'm an autodidact and have had the technical side of things mastered a long time ago & lately have been reading up on things like receivables factoring / equipment trust certificates / negative cash flow conversion cycles and stuff like for example the things listed here; Dotcom/blog/category/telecommunications/what-kind-of-lending-companies-fund-the-telecom-industry/">https://www.1stcommercialcreditDotcom/blog/cate…

So how does one transform a small private company where customers now have to pre-pay several months ahead for widget/infrastructure (lots of friction/limited potential); to something more sophisticated in the financial sense comparable to the way cellphones get subsidized, aircraft are financed etc.

I have made a list of firms that provide these kinds of services and are most closely related to my niche market/widget. But i don't know if its smart to already call/email them since i still feel way way way, out of my comfort zone.

Any blogs/forums/threads/books that i should read? Names/job titles of specialized people to consult/hire that could assist? What are the possible reasons that these services are not used more? What pitfalls to look out for?

I know there probably are a bunch of people that know much about these things in the context of big established public companies in big established industries; i'm more thinking of things in a startup context (new small private company in a new industry)

According to the four stages of competence it seems I'm currently consciously incompetent, does that mean that its time to start making mistakes & embarrass myself by just starting to call/email around?(to leanr as quickly as possible)
