Garden Design Ideas

Hi I am looking for best software which can create easy to make professional looking 3D landscaping and Garden designs. The software should have everything ready to copy paste or insert for making designs. Their should be option to give the size according to our need and use curves and slops.
Also looking for websites which has photos of landscape garden patio designs free download.

Thanks for all who answers.

I am redesign my garden and I am looking for a program that I can download to design my garden something like the Sims (or Lego if your an 80s child) any ideas??

Which of these software packages would be best for me? I have a small garden design business, I work solo (no employees), I carry no inventory, and have few expenses. I invoice in excel now, and my terms are net due on receipt (so no A/R). I just need something basic to track income, expenses, sales tax, and my bank account. Which would you recommend and why? Also which version of each if possible, they all have different levels and versions. Thanks!!!
