I liked the simplicity of the #74 and also #77 for smart playing in negative space of H, and a modern sense of #116, but according to the field of my expertize of branding, is easier to make numbers of design of #74 and #77 in a pillar in the construction of brand image of your business because of flexibility to deliver something, but somehow don't know what kind of business concept that you want to run, so it can provide more specific design direction.
but guessing from all the briefings you gave, I think that you should have a logo with one dominant color (black, maroon, dark green, royal blue, etc), memorable and timeless, other feelings in the logo can be added later as needed.
