This site has something called hortinova trellis. I'd suggest this stuff for super easy long lasting trellis.
Then pretty much prep soil like you would for growing anything else. So basically in your climated I'd recommend you use a product called stylet oil if you have bugs. This is what organic vineyards (and the non organic version for conventional vineyards) use. That's the main thing I can see being a problem. Your humidity may cause mold. This can be resolved by another organic bacillus subtillis bacteria product called sonota early in the year before the clusters start to form and once they start to build clusters so that the bacteria is there to compete with grey mold as it starts. There are some other good ones too though that can keep grey mold or bud rot from happening during sweaty, humid, and rainy weather. Arid falls are why we can grow these types of things here without mold, but on the east coast where warmer ocean and weather brings humidity up really high will affect potential molds. Especially since you get lots of rain in the hurricane season/summer. We typically don't see rain until late september after the harvest time for hops I think.
I'd say buy some bulk compost, dig up a small hole or trenched row if you are planning on getting more than a few plants in, maybe 6'' wide x however long and put amendments in like ones that will cover your npk and micronutrients, etc. short and long term, setup a drip system because it will need lots of water and cover with compost and mulch 4" thick. This will allow other things you need to support your plants to happen, earthworms, microanthropods, beneficial fungi, bacteria, etc. Things that will keep your oils high for better hops product. Remember, the compost and the mulch will help keep your plant consistently healthy while the weather changes blaze, which will make the biggest yeild increase.
Here's what I would suggest if I were to get serious about making my own hops.
steamed bone meal
sulfate of potash
calphos (soft rock phosphate)
Glacial Rock dust
