Bad news mate, crafting weapons is extremely hard and generally worth it only for either super budget or on the opposite end, high end "deterministic" crafts using whittles and costing several mirrors to finish.
In the current economy, perf exalt slamming and anuls are actually the best way to craft as both are unusually cheap so: anul to 1 mod and chaos until any t1/t2 desired mod (preferably phys prefixes), then slam perf exalts and yolo anuls to try and git rid of bad mods. Rinse and repeat, if you manage 2x t1/t2 phys prefixes, desacrate for the last one or if you have a bad 3rd prefix, omen of sinestral necromancy + jawbone try to snipe it. Failed? Restart. You have good odds for full t1/t2 weapon within a few hundered divs. It will take time though
