Buenos Dias Fernando and welcome to the Cow Audio Forum.
LOTS of things to consider. Buying a guitar, itself, is a big deal. Do you play now? If you already have an acoustic guitar, you can have it rigged with internal pickups. You need to be very choosey because some pickups don't sound very good.
I like the K&K Pure Western Mini system. I had it installed in my Martin a few years back. Here's a clip with those pickups:

You can see the video of me playing the instrumental while sitting on the couch. That was using a Schoeps cmc641 mic. You can see the tip of it on the couch arm.
You usually get the best results from going to a direct box and then to a mic input. The direct box converts the normally very high impedance of the pickups to balanced mic level. You'll get sound even of you don't use a direct box, but it won't sound as good.
There are a few guitars with electronics that make a direct box unnecessary, but none come to mind at the moment.
