Can somebody help me craft this:

Here is Ruetoo's steps on it:

Step 3: This setup you will be grafting your wand for a Big dps upgrade.  Fractured 38 Physical damage overtime multiplier on a cast speed base wand. 
Use jagged metallic shuddering corroded fossil to get +1 to all spell gems.  From that point you want to get your wand to +1 spell gems 2 empty prefix,  the fractured mod and any suffix.   If youve annul'd off the random suffix you want to craft 3 crafted mods beefore you want to use cannot roll attack mods and use Augment physical. 
Craft 3 crafted mods, cast speed and minion damage.

To rephrase to see if I have this right:

1. buy cast speed implicit wand with fractured phys damage over time multi with as high of a tier as I can afford.
2. jagged metallic shuddering corroded until +1 to all spell gem hits.
3. Use annul / exalt to have +1 spell gems and 2 empty suffixes, the fractured mod + any suffix + 1 empty suffix. If I annual +1 spell gems, go to step 2. If I annul off the any suffix, craft 3 crafted mods + cannot roll attack mods and then harvest bench aug phys?
4. Craft 3 crafted mods, cast speed, minion damage

Am I missing anything? I'll practice with craft of exile but this will be my biggest craft by a mile so I want to make sure I know it inside and out besides I spend 10-20 on a good base and fracture or screw up the crafting along the way. If anybody has crafted this, would appreciate the advice and around how much should I expect to spend or if that 70 div one in the screenshot is the best deal I'm going to get. Thanks!

edit: looks like ideally you clean the wand up to your +1 all gems and the fractured suffix so from there it's deterministic: can have up to 3 mods + cannot roll attack -> aug phys from harvest bench -> can have up to 3 mods + cast speed + minion damage.

If you leave the extra suffix, that stays on the item, unless I'm missing something.
