I need a sketch up expert -- 2

Job ID: 36087157

Budget: £20 – £250 GBP

I have built a model of a garden but it needs sharpening up. My sketchup up expierence is limited and so may need fundemental flaws correcting.
I am using it to present the concept, and ultimately i will use it to quanitify off so the overall size of the model needs to be kept as supplied.
I would like to provide some images as how i want the railings and staircase to look rather than the models i have imported to use.
