Force India insist talent and not sponsorship is the vital criteria in deciding their second driver for next season.
Having lost Nico Hulkenberg to Sauber at the end of the 2012 Championship, Force India are in need of a new driver to partner Paul di Resta.
Several have been linked to the team including test driver Jules Bianchi, former driver Adrian Sutil and Kamui Kobayashi.
However, when it comes to making the decision, chief operating officer Otmar Szafnauer insists money won't be the deciding factor but rather they'll be signing someone who can push di Resta.
"I am a believer that you need someone like that," Szafnauer told Autosport. "Not everyone does, and it is a subconscious thing.
"You think you are driving the best you can, but there is nothing like competition for us humans to really sharpen our focus, attention and skills in all sort of stuff.
"If you have competition you end up driving yourself more."
Szafnauer added: "We will announce everything in a couple of weeks. We have a pretty short list of candidates now."
