Non-dilutive funding and return on time

My new business (LegupHealth ) is ramping up. I'm starting to think about how I'm going to finance it until it's profitable. I don't want to give up any equity at this early stage, so I must consider non-dilutive funding options.

By non-dilutive, I mean funding sources that don't need me to sell or give away ownership in the company (i.e. equity or stock). Examples include personal savings, cash flow from other endeavors, and bootstrapping. Other sources include grants, pitch competitions, debt, and profit-sharing arrangements.

As I rank the various funding sources, I'm realizing how important it is to consider Return on Time (ROT). As a solo-founder, my most precious resource is time. So, I should invest time in efforts than have the highest ROT.

When evaluating a funding source based on ROT, the obvious return is money. But I must also include other returns like new relationships, exposure, and credibility.

For example, should I spend my time working another job to bring in cash flow? Or should I spend my time acquiring new LegUp Health customers to bring in cash flow? Or should I spend my time applying for grants and competing at pitch competitions to bring in cash flow?

The return on time for each of these efforts is not obvious. But it's probably worth my time to estimate it.
