According to USPS from CRAWFORDVILLE FL 32327 to CRAWFORDSVILLE IN 47933, guessing the zip code, as long as it fits in their USPS produced envelope it would be:
Priority Mail 2-Day™ Flat Rate Envelope USPS-Produced Envelope: 12-1/2" x 9-1/2" $5.60
Thats a rough guess. Pretty sure it will fit. Next one up changes it to $5.75. Not a big difference.
