Bran won't work, you need something that's been
malted - started germination which unlocks enzymes and starch reserves. Either malted grains (which need more equipment to process) or malt extract (where the starch has already been converted to sugar, so less work for you and less weight to ship even if the beer won't be _quite_ as good).
Malt is much the heaviest ingredient (aside from water, which is another conversation...), so it's the one where you will want to try and get it locally if you can to minimise shipping costs, I imagine shipping from Europe (Italy? Croatia?) will probably cost more than the malt itself. Are there local maltings supplying Heineken? Perhaps they will sell direct to you??? Although they will probably only sell malt grain. Might be worth another look in the healthfood shop, or talk to them to see if they can get malt extract through their suppliers?
Yeast - you have two main choices, dry or liquid. Dry is much cheaper and easier to ship, but there's a much smaller choice. So it depends a bit on what kind of beer you want to make, but something like Fermentis Safale US-05 is a solid "ordinary" yeast for US-style beers.
Fermentation temperatures also matter - most ale yeasts give best results around 18C, Belgians can go a bit warmer, lager yeasts need cooler, but if that's a problem for you the one liquid yeast that it might be worth you making the effort for is Omega HotHead OYL-057, a Norwegian strain that is claimed to make clean beer even up to 37C. I know that's chilly by Egyptian standards, but if temperature control is a problem then it could be one to consider.
The good thing about yeast is that you don't need to buy fresh every time, you can culture it - it needs a small amount of extra equipment to start with, but then you can keep it in a "library". Even just keeping the slurry from the last beer can work for a few generations. But initially you may feel more comfortable just buying extra packs, it's one less thing to worry about.
Hops are a problem, you will pretty much have to import those, about the only hops that might possibly grow in Egypt (and then, only on the coast) are the South African ones which are day-length insensitive.
I guess Czech or Italian stores may be the best ones for you from a shipping point of view, but I don't know those markets; in the UK both
Brew UK and
the Malt Miller have a good selection and reasonable prices,
Brouwland are based in Belgium (so understand French

). I don't know what any of those are like for shipping internationally.
