Coding a theme is not something that can be done in a few minutes. Time is precious for most people these days.
If you really want a custom theme you could always start building it yourself. It will take some time to get the hang of it, but HTML and CSS aren't the most dificult languages to learn.
And like GHengeveld already pointed out - people here on the forums are always willing to help if they can provide answers to your questions.
