Activity for GoldenBride

Not sure if this is the right venue, but does anyone know of an app or program that will allow you to visually draw out a set up you envision in a Backyard or something similar? I can draw it on paper, but I'm pretty sure I draw like a 2nd grader,...

I'm planning a wedding in our backyard in Stockton and relatively new to the area; anyone have suggestions on vendors reasonably priced for drapery and lighting. Going to have a tent. Guess it would be best to have a package deal... one stop shop.
