VFX for VR (URP Compatible) in Unity

Hi! We are looking for someone to create Visual effects for our new VR app (Platform: Oculus Quest 2). We have a list of 3-5 VFX, including particle effects and animation. For an example of the scope and style of work we need, see the 4:40 mark of this video https://www.youtube.com/watch?v=onBKizkzsLg&t=317s - a particle effect representing breathing.
