First lets ask some questions so we can recommend what the OP wants, just sand won't get you some results as opposed to something like Aquasoil or Azoo plant grower bed.
What do you want the tank to look like aquascaped pretty much means you designed it. I could throw rocks in a tank that are put together nicely, put anubias in between them and say it is an aquascape, almost no work, and can look really nice if down right. What type of maintenance are you willing to do? A high light tank will require more money, more experience, and more work compared to a lowtech tank.
You need to really tell us more than aquascaped.
