Congrats on the graduation and starting your planning journey! You will find a ton of information here that will help you out in so many ways. The ladies here are great and the review sections are worth the time to read!
Definitely find a good travel agent. They will become your best friend through your planning process. If you're in the US, the owners of this site are pros in the destination wedding area. If you're in Canada like many ladies here, then you'll get a ton of recommendations on TAs in whatever area you're in.
Good luck and happy planning!
