I overlooked your location (Ecuador). Patagonia malt is very nice as well; uniquely nice! IMO, it's not as (how should I say) "plain" as other specialty malts so it can be overpowering in some recipes, but then there are the instances when it makes the world of difference. I would hope that you could get those malts there pretty easy.
Also, in regards to liquid yeast, shipping, costs, viability and such. I remember a thread where folks where swapping liquid yeasts IN DRY FORM; specifically to pass along several strains for the cost of one stamp; and also had the benefit of not degrading their viability nearly as much. I'll have to find the post and provide a link.
My recollection says it worked something like this:
-Using sterile blotter paper (1cmx1cm or so)
-highly sanitary conditions
-a small (dilute) drop of liquid yeast is placed on blotter paper
-the paper is dried in some fashion (quickly?, near a heat source?, somehow)
-the paper is wrapped in a sterile piece of aluminum foil
-put in envelope and mailed
-Upon receiving
-using highly sterile enviroment
-the paper is trimmed and yeastiest part is stirred into a small volume, low gravity, sterile wort (15ml maybe)
-allowed to build incubate and become active
-then built up to full size through a couple step-ups
-at which point you can plate, freeze, refrigerate, etc
If I can find the post I'll provide a link.
