You are going to have to be more specific regarding height concerns.

we are very limited if you are asking about local nurseries ...

or are you asking about cultivar.. name.. suggestions???

if you want a specific form.. you might be best off visiting high end local nurseries .. and see what they offer ... rather than picking a name.. and hoping you can find it in the form you want ...

if you want something really special as to form .. you might need to talk with the store manager.. and have it ordered in on their next delivery ... which might be fall.. which just happens to be the next best planting time ...

You might also add COLOR preference. They come in so many colors..., red, pink, pale pink, dark pink, magenta, white, coral, lavender, purple...

I am in the NJ/NYC Metro Area and you can easily purchase many cultivars in local nurseries (sold mostly from May through August). I have have good luck with the following in the Greater Metropolitan area...

Zuni (magenta)

Catawba (purple)

Dynamite (bright red)

Hopi (medium pink)..., one of my favorites but not exactly "compact".

I'm looking for something not much more than 12'. Originally I was looking for a weeping type of tree which my neighbor's brother has and she wanted the same tree. Sadly her daughter passed away and I offered to buy the tree in honor of her daughter but we have limited space.

My neighbor thought her brother's tree was a weeping Cherry tree but I found that one to be too large, her brother's tree is only about 6 to 7 feet tall. Upon more research I thought it was a weeping Wisteria tree which would fit the description. But those trees are limited in nurseries and as far as the net I'm not comfortable buying trees from the sources I've found there.

But my neighbor ultimately left it up to me as for the tree type so I went looking for a dwarf blue spruce tree, which I did find at a nursery called "Baby Blue Spruce" which reaches 10' in ten years according to the tag. However, I looked it up and several places suggested it gets from 30' to 60' tall! I also found Blue Wonder Spruce which would be the perfect fit but once again the only source is the net which I'm uncomfortable with as far as trees go. Finding the right tree and size has become challenging.

The Crape Myrtles were another option and there are sources where I might purchase one online or at the nursery, but my neighbor wanted a tree and some of them look more like shrubs. Although she said that would be okay but I still wanted something more upright in tree form and something that's also compact enough for our area.

The colors of interest are purples, lavender, pink and blue, thanks!

Be very careful of the variety of crepe myrtle that you chose.

Right now I have a crepe myrtle that was suppose to remain small that is a good 30" tall. (over the eves of our 90 year old church). To the best of my research it is only 25 to 30 years old.

This is but one example of these large crepe myrtles in this and other areas of the south.

Thank you for the recommendations everyone. After looking everything through we decided to try 'Purple Magic'. It may not be tree form but on second thought it might work out better for our area.
