My friend and I make all of our cosplays, and if you have no other option we could probably make it for you (assuming we have the time) but making cosplays yourself is really rewarding so I encourage you to try it yourself first :3
Soren's Radiant Dawn outfit isn't too bad...you can always make the blue robe-dealio with a dress pattern with long flowing sleeves like his and then add the slits in the front. And to put the design on you could sew it, otherwise they make this stuff that you can put on the back of the fabric to make it iron on and stay, or just use fabric glue. I've had lots of luck using all of those methods
Let me know if you'd like any more suggestions :3
Good luck with your cosplay~
