Hi Ash & welcome. I'm actually working on a guide that would probably suit you down to the ground, but it is a few days off being complete. It sounds like you might've brewed kits before, if so you'll have a fermenter and just need to be able to fill it? Also, let us know what the recipe is.
As you indicated you're not fussed on all the equipment or building things, I can highly recommend the BIAB/ stockpot method. You can pick a BIAB bag up through AHB site sponsors for less than $10, see the banner of the top of the page, 19L stockpots are about $20 at big double u style chain stores etc. There are no modifications necessary to the pot, the bag is best with a drawstring but not entirely necessary. You'll also need a thermometer, the important range to cover is 60 - 75 degC, having a large sieve that sits in the top of the fermenter would be good but entirely necessary to begin with.
The method (simplified):
1) Heat the water in the stockpot, about 3/4 full, aim for about 4 or 5 degC above the mashing temp in the recipe.
2) Put the bag in, secure it around the rim, add the cracked grain and stir, check temp. Insulate it well then let it sit for at least an hour.
3) Carefully lift the bag out, hang it over a saucepan or bucket to drain, squeeze it with gloves to get a much of the liquid out and add that to the stockpot.
4) Put the stockpot on the stove, you need it to boil for an hour while adding the hops as per the recipe. Before the boil is finished, put the lid on partially to sanitise it.
5) Once the boil is finished, put the pot in the laundry tub and add water to cool, change the water a couple of times to cool it to room temp, leaving it overnight is good.
6) Pour the cool liquid through the sieve (to catch hops debris) into the sanitised fermenter, add the yeast at 20C.
7) Leave the fermenter in a dead fridge/ a cool spot where the temperature is about 20C until fermentation is complete etc.
This method doesn't need any fancy expensive equipment or difficult building of stuff, what you do need is all easy to obtain and doesn't need modification plus you can make excellent beer. In fact, I use this method all of the time, although with a few slightly different steps (sparging etc), but you don't need to worry about any of that for now. This way you can have a go it all- grain brewing to see if it really is for you, if it isn't then you're not out of pocket by hundreds of dollars and then also have some largely- useless equipment, if it is then it is just onward and upward!
