Do the tier 1 manually, it will take you some time and effort but it will pay off in long run!
Here is what you need to do
1. build 5-6 web 2.0s to start with and add 1-2 unique articles (700+ words) to each one of those with a link back to your website and also link an authority site like wikipedia!
2. Submit 5-6 unique articles to article directories
3. Convert 2 -3 articles into a pdfs and submit those to document sharing sites
4. Create a facebook page, twitter, pinterest and do some social signals
5. Post your link to 20 - 30 bookmarking websites
6. Create an rss of your page and submit it
All the above you can and maybe more you can finish doing them manually in one month, and slowly and steady you will start to getting backlinks
Then you can buy a service from here and target your tier 1 links!
Good luck with what ever you decide to do!
