Have you purchased a link pyramid service here or on Fiverr? Satisfied? I'm looking for recommendations. If you offer such a service feel free to PM me. Also interested in .edu domain backlinking. I'm a good client, pay up-front and don't nickle-and-dime over services.
Here's my own recommendation: kudos to Brilli22, he PM-ed me with an offer, I took him up on it and he did a magnificent and very quick job! Highly recommended, I'll be buying some more from him!
