I wish I was Mario, I wanted to do the same. I had a four foot bow front Jewel aquarium I was going to aquascape in a big way. It sat in my office for 3 years and the only thing it had in it was a dead fly!

Life gets in the way these days, so I sold it! A shame as I too had plans. There are some good books out there, check Amazon for used copies, always a bargin. Let me know if you need supplies of aquarium stuff as I have access to a good supplier

Now, aquascraping ponds, that's a whole new thing, I'm your man.
