over apped...suggestions for one which will work for this weird purpose?

Hi!
Thanks for creating this forum...I need some help.
I am looking for an app which will help me with my business. I create logo mats and mats for homes etc. (adoremat.com.au)
I want to be able to show customers on my ipad how their mat may look by uploading their logo, or by writing a text (eg. Welcome) in a few different fonts.
The background i need to fill with a solid dark colour usually.

Sounds easy enough, but i'm not sure which app..??
Below are two examples of logos which I edit.

On my Mac I use photoshop elements.
Any and all help appreciated.
kind regards
Rachael.

 

I don't have it yet, but you might take a look at Adobe Photoshop Touch.

 

There is an app called logo maker, where you can upload the logo using the camera.

App Store - Logo Maker
