dabigg, welcome to the board!
Hopefully you can do something soon about not having the "right height grill". What you made sounds good but it's still missing something, the wonderful smoky flavor of genuine "Q". What type of grill do you have? I'll bet we can figure out a way to get a bird in there.
Maybe you can take the main food grate out and set a couple bricks on the charcoal grate and place a smaller food grate on the bricks. This should lower the cooking surface and allow you to get a chicken under the hood.
If nothing else, work it in the budget to add a smoker to the family...you'll love it!
