Model and texture 30 boulders for low poly game

Hi I am looking for someone to model and texture some boulders to be used in a video game (Please see examples attached). They will be all modeled from specific references, and they must look like the reference provided. I will not accept generic boulders or stock models. If I need to send them back for edits more than 3 times then I will have to cancel job and find someone else. The boulders also MUST be low poly and have a diffuse and normal map texture (No spec maps required). Please say 'Cherry Lollipop' in your proposal so I know that you read the instructions and aren't a bot. I will not be accepting any models without the normal maps. This is a low poly game and so the normal map is important to keep the polygon count low. If you don't provide normal maps I will not accept the model. Budget is tight, I am sorry the bid range is what we can afford, but hopefully these models will be easier for veteran modelers and will be quick to do. If you do this job well I will hire again for more. JOB REQUIREMENTS 1. Sign an NDA 2. Use Dropbox to share files 3. Good communication via freelancer or Skype 4. Knowledge of how to set up normal maps 5. Knowledge of Maya or any other modelling program
