Hi there, I'm Vanessa, designer. I want to offer my help in the design of your shed. You said you have ideas and pictures, it will be nice if you share that info so I can have a better idea of what you want. Also, want to know dimensions and other important things for design. I can offer to you first the 3D, and as you said, if you like my job, we can move on with profesional drawings...I have experience working with architecture and structure drawings, so I can help.
Please, feel free to contact me to discuss more about this, I will love to help, really. I can share samples of my previous jobs also.
Have a nice day!
