Question on getting from 225-250 EnchantingFollow

Hi to all the experienced Enchanters here on the forums.
I've just got 1 question, as I'm preparing materials to get from lvl 225-250 in 1 sitting when I get there to the trainer in ULD.

I'm wondering how much mats should I bring so that I can complete it in 1 sitting? This is my planning please let me know if it'll work thanks ^^

This is my format of my planning

<lvl I'll be doing that enchant> <enchant I'll be doing> <(lvl which I learned)> <times I'll be doing it>

From lvl 225-230 Enchant Boots - Stamina(215)x5
From lvl 230-235 Enchant Chest - Superior Health(220)x5

total vision dust I need 55, will bring 100 vision dust incase I can do more that allows me to skill up.

If I can't skill up any more, I'll continue with the following

From lvl 235-240 Enchant Shield - Greater Spirit(230)x5
From lvl 240-250 Enchant Bracer - Greater Strength(240)x10

Total Greater Nether Essence needed = 15
Total for Dream Dust = 30

Please let me know if my estimates are correct?

All the enchants above 225 can be learned from the trainer according to thottbot and I've picked the cheapest enchants for lvling >.<

I'm only lvl 21 right now, so I've got 14 lvls to pre plan and slowly buy up the materials/disenchant the materials.

But I'm a person who likes to pre plan for the future, another reason why I want to do it in 1 sitting is because I'll be 'begging' for people to bring me there once I hit lvl 35, as I don't have a strong and powerful Guild.

In fact I don't have a guild right now. So would really appreciate any advice to either lower my cost(i.e. cheaper enchants that I may have missed out) or correct me on my estimates.

I'm sorry if this question has been asked before, I've looked up to page 3 of the trade skill forums and gave up, as I don't have a search function cos I'm not a premimum member.

Thanks in advance! ^.^)/
