Create Visual Effect for A Game

We are currently developing a game which has been 70% finished. What we need help at the moment is creating some effects for it that will enhance the visual and user's experience. Thus we URGENTLY NEED a 3D Effect Artist Freelancer, specialized in creating visual effects like explosion, fire, lighting, and particles for games. We are very open for any discussion about the budget, payment term, and working scheme. Show us your interest and let's work together!
