I need some OB woodworking help

So I am trying to mirror this trim that goes around the outside of a window on my house. There were already pieces there, but unfortunately they all broke in two when I was taking them down to tint the windows. I kind of used them as a template to cut out the new pieces, but since I had to use a jigsaw, the edges are a little wavy. I don't want to put this all back together and have it looking like shite, so I need some help on how to smooth out the curves
Here is a pic of one piece. I don't have much room to take out more wood and create a whole new curve. It's an angled pic, but the curves are almost completely flush inside and out.
I've got a router with a cutoff bit, but I'd need a perfect template to use that, which I cannot make. I could sand it, but it wouldn't turn out perfectly curved.
I also need to put some 1x1 trim around the edge of the curve, and I need some advice on how to make that too.

You need to make an MDF template. You should be able to figure out the curve with a center point, string, and pencil.
Then use your router and cut off bit with a bearing.

3 tables, a string, a buddy, and the router. Used to do very similar for garages.

I was thinking about buying a dremel the other day for a similar issue. Not sure how it would work out, but i know there are atachments for sanding wood

I've got 3, and it wouldn't work because there is no way to tell what's perfectly circular and what isn't

How would I make sure the router is cutting a perfect edge on the mdf for the template?

Use the string and pencil to get your line on the MDF, use your jig saw to cut out a rough edge on the template then use either a bastard file or a sander to get your edge smooth and to the line.
Fix your plywood to the MDF template with two way tape and set the router's bearing to run on the MDF template.

Disclaimer: I'm no finish carpenter.
Can you put some kind of wood putty on it and smooth it with that? Is it to be painted?

It's a little hard to tell exactly what the window looks like without the trim piece. If you have a flat rounded edge all the way around the window, you can screw a piece of MDF over the area and use your router with trim bit and bearing to follow the edge of the window. This will provide your template.
As far as the 1x1 trim. If you're considering using something like 1/4 round, you can cut kerfs in the back of the moulding every inch or so, and you should be able to bend it into place.

I think I figured it out, but this is gonna be a huge PITA. If I could sand the edge smooth, I would do that now, but I can't.
I'm gonna:
Trace
Find center
Make something to mount router on to cut the perfect arch
Cut the mdf with a router
Mount the wood onto the mdf
Ride along mdf to smooth out edge
Does that sound right?
Should I just try and find a woodworking shop to do it?

If you can get a good tracing, a cabinet shop with a CNC machine can probably cut the pieces for you.

You can rig up the same with a jigsaw, but the results aren't as good.
Screw the jigsaw base to the radius template.
Just smooth it out with some 50 grit sandpaper followed by finer grits.

The pieces aren't attached right now. I have everything else done except these arches

That would work, but if you have the router attached to a center point you wouldn't need the MDF template

Just talked to a buddy that's a GC, who owes me a favor. He's gonna send his finish carpenter over this weekend to get it done 
That would've been a major PITA
