I would say you fly over there.
You need to either fly to the San Pedro Sula airport or Tegucigalpa airport. Then you need to go to Siguatepeque, probably find a hotel there, and go to the Capilla Evangelica in Siguatepeque, Honduras. You might need to have someone help you with the language or if you speak Spanish then that would be no problem. There is only one "Cementerio General de Siguatepeque" there. It is located at or near the main entrance to Siguatepeque.
Here is a web site that has two hotels. It's in Spanish though, but I'm pretty sure someone might speak English there because there are several expatriates from the US living there.

Even though there is information online saying that it is better not to go to Honduras, it is not completely true. You can still travel there and be able to do what you need to do, as long as you do most everything during the day time and accompanied by other people you trust. The more casual you dress, the better. You will find that some people are very helpful.
