Using services or buying tools and do the work myself?

Hi,

currently I'm running 12 MNS. Each one has about eight articles on it and I have another 2 in queue for each one.
I did on-page SEO, adding articles regularly etc. So I think it's now time for the off-page SEO.
My question is do you think I should use (BHW) services for that or should I buy some tools and do the work myself?

Also I already did some calculation:

Using Services
(price for all-in-one seo services about $30 per site)

12 Sites * $30 = $360

Buying tools

$89 GSA Search Engine Ranker
+$67 Wiki Bomber
+$77 Captcha Sniper
+$0 Creating Facebook, Twitter etc.
+$?? Private Proxies

= $233 + Private Proxies

So I think it would be better to buy my own tools and do the work myself.
Especially because I have to buy the tools just one time and can use them how often I want.
Also I'm going to learn a lot of things and gain experience during the process.

Am I correct or do I have an error in reasoning?

The only answer is how precious is your TIME.

If you have time to learn and configure those tools then go ahead buy them. If you have a day job or something else you are busy with, then I recommend the services.

Which is more precious:

$233 + your TIME

or

$360

why not do both

More links = more rankings

In my opinion , you should buy the tools and do the work yourself. Not only will you learn about building backlinks to your site but you'll also get a feel for what works and what doesn't.

Try and work out what you can do efficiently and buy the software that does that, then outsource the rest. Then you get the benefit of both options.
