Hello! My name is Warren Schultz, and I am a professional programmer with many years of experience using Python. I have read your project description, and I can create the Sentence Extraction program you have described. To do so, I will use Python's Natural Language ToolKit (NLTK). I have written very similar programs in the past, and I would be happy to show examples. Please contact me so we may speak further and so I can send files. Thank you for your consideration.
