G autocomplete/suggest

Hi, all. Step by step, I'm rediscovering what works in terms of SEO (and what don't any longer)... thanks to a some great people here (guys, you know who you are: I 'd so gladly return the favor, you just have to ask if you think I can). Well, for the time being, I'm desperately trying to find a service able to safely influence G suggest/autocomplete with one legitimate keyword.

There's long been a reliable service like this in the past, but it now looks shady, the latest reviews are not that good (at all), plus there's no way around automatic billing, and I hate that.

For a brief moment, I toyed with the idea of using a microworking service, but really I prefer having recourse to a third party for better anonymity. Many thanks in advance for your responses (do not hesitate to contact me in private).

I am curious if you already found a service like that. I am searching for the same thing..
