We’ve never seen any theme offer that layout out-of-the-box, so no matter what it will likely require child theming. It almost sounds like you want a grid layout:

Which we could easily help you customize to have as many columns as you like. Or perhaps you’re more interested in a magazine style layout?
Could you share examples of sites using this layout which you like, would you be willing to let us see if we can create this for you, or would you simply like a refund now?
Thanks
