Hello,
My name is Sam and I am very well versed in Unity3D. I have been working in Unity3D for 3 years and currently build fun and serious games including 3rd & 1st person levels. I am a pro with lighting (Light Maps), memory allocation (Occlusion Culling), scripting (C#/JavaScript), Database-Driven architecture, Augmented Reality Unity3D apps, and importing 3D models and textures. I can work in Pro or the Free version. I just got back from the Unite 2012 conference in Amsterdam!
I can meet the $100 per level requirement but am interested in the complexity of the level design. I would also need to know the platform this will be built to for level optimization and supported screen resolutions.
Let me know if you have any questions!
Sincerely,
Sam
