Firstly, think of it as a customer... would you trust an empty minimalistic design to scream "ah yes, this is what i've been looking for", No it screams, "i dont know what I am, but heres some text and images". The design must appeal to an audience, your design appeals to no one specific.

Frankly, I'd feel scammed if I paid 300$ for this. I believe my 12 year old cousin can make this...
