Hello, Client.
I think you are going to build an sketching app.
This is a protel style app.
I've already experienced in this area for Mac OS X.
The main point is:
drag and drop elements.
I have some questions:
- Do you try to make iOS version or Mac OS version?
- I am not a good designer, but good coder.
So you should to provide all design images.
but I can do simple interface.
If you are interesting my work, please let me touch.
Thanks for your consideration.
Best Regards.
Ion.
