You are doing exactly what I am as well, and creating a savable form. Although it is a slight process, it is very do-able.
1. First create your form in LiveCycle. Once finshed, save it and close down LiveCycle. (e.g. you should have "Document1.pdf")
2. Open your new PDF with Acrobat Professional. Make sure you see the fields, and then add Usage Rights to the document (Advanced - Enable Usage Rights In Acrobat Reader).
3. It will ask you to save it, so save it as something else. (e.g. now you save it as "Document1A.pdf")
4. Then the KEY is to chose File - Save As and save it one last time as another name. (e.g. "Document1Final.pdf")
5. Close Acrobat Professional and open your final file ("Document1Final.pdf") with Acrobat Reader. You should be able to fill out and save the PDF, so it can be emailed back as a filled-in document. At this point you can make a copy of it and name it whatever you would like the customers to see ("BobsRequestForQuote.pdf")
Remember not to save over your final document (or you will have to recreate it), but keep it in a safe place for sending out to customers. Sure beats handwritten forms sometimes!
