salesforce trigger/class/unit test

Hi, Attached, you will see a jpg that illustrates what I need. I need to email the PDF attachment to the Person Account's email when a new opportunity is created with type = 'Banking'. The email should be using a preexisting template with email template name = 'Bank Enrollment Email' I need the class, trigger, and unit test for this. ------------------------------------------ I have many more small/large projects that I will need help with in the future and I hope to build a relationship with someone for ongoing work. This would be a good measure to see if we can work well together Thank you for your consideration
