I am having trouble finding a work around to get this part into a usable flat pattern. I received the part originally as a stp file. I am running autodesk Inventor 2010. Any help or advise would be greatly appreciated.

Redraw it in Inventor using sheetmetal tools. It's a pretty simple part, you've probably already spent more time trying to unfold this then it would take to redraw it. Use contour roll.
Will the holes on the non-planar face be machined before or after bending?

You will have to use Contoured Roll and Unfold/Refold (and perhaps a bit more) to get this design.
Because you are using older release someone will have to demonstrate with images how to model the part if you can't figure out the sheet metal tools.
Becuase this is a compound bend Inventor will not flatten it unless it is modeled using Inventor Sheet Metal tools.

I have been attempting to remodel it in inventor with no luck (honestly I do not even know where to start). I have never used the sheet metal tools in inventor to model a part before.

Was there a Sheet Metal Tutorial under Help>Learning Tools>Tutorials and Skillbuilders in v2010 that covers Contoured Roll feature? The Help screen might have additional information besides the Tutorials.
Give it a first try and then attach your attempt here. Someone will walk you through to the finish.

This is what I currently have on my screen. I have tried using the bottom planar surface but I am not able to make a sketch on the edge I think I would need to go off. I am having the same problem with this piece though.
Here is the bottom, I just don't see where to sketch my profile for the roll nor do I understand how someone knows how far are to draw the axis line.
Your help so far is greatly appreciated. Thanks
Forget the surfaces and the imported geometery.
This is the basic shape, if I remember correctly (with made up dimensions).
Once you have this, we'll need to do an unfold and then locate and create those holes followed up with a refold.
This dimension doesn't really make sense, and to paraphrase from JD, is not a manufacturable or inspectable dimension. What's needed is a tangent constraint on that arc. I also question the .753, but that may be appropriate depending on the design intent.
I hope I'm not frustrtating you with what may seem like nitpicking, because it's important to get these kind of things right before we move on.
The .753 is how I would inspect the height of that feature using a height gage however I did add the tangent constraint. I appreciate the nitpicking. That's what it'll take for me to learn how to do this correctly so the next time I get model like this I am not back on here taking up someone's time again.
That makes sense for the .753, what about the .835? How would you inspect that?
That's a good attitude to have.
I constructed an itersection point on the customers model to figure out how long those two legs were and thats what I used to base my sketch off.
