Sure, you'd need to hire someone to do the logo and the custom icons, but I am certain that would not cost you anywhere near $46k.
Furthermore, I cannot comprehend how this actually happened even if you shared all the details. Holy shit, for $46k you could have gotten the spaceship-equivalent of a design from someone who actually loves what they are doing.
Mate, $46k is annual salary for A LOT of people. In the amount of months that it took for them to "finish" the project, a junior dev could have picked up design chops and done a 10x better job at this.
Just wow....
ALSO A QUICK EDIT:
If anyone needs design work done (best I can do is a checkout page with a bunch of unstyled ordered lists) my pricing starts at $40k per 8 months, which is a lot less for what the author's company was charging him.
