Haha @ everyone in this thread trying to sell spam services to rank. Stop it. OP it's possible but if you want long term ranks you need to manually build your links. Even if it's only tier 1 manually built, it has to be manual or it will be deleted out. Two things you need to understand.
1. Keyword diversity. You need to have it perfect of you'll be penalized.
2. The pace you build all the keywords. If you build them all at once, that's going to be a ton of links, try drip feeding, go one at a time for each keyword.
Goodluck and feel free to PM if you need further advice.
