I am looking for videogames to bring to market (publish and
distribute). How do I go about finding video games
designers/programmers to contact me who seek to bring their original
video games to market (commercialize)?

I would try posting an ad in either a University newspaper or posting
flyers at a University Computer Science building.

The Video Game field is wide open and subject to very new idea's that
can and will thrive. Considering I don't think you can contract with
and of the big companies such as Sega, EA, or Midway, your best bet
would be publish a want ad in a largely distributed national newspaper
chain. This would attract people to submit their idea's to you. You
could also go to online websites and post a need for a gaming
designer.

See which universities do a degree in computer and video games (such
as salford university does). They will be happy to put you in contact
with third year students as it will increase their graduate employment
rate.
Consider advertising on www.gamasutra.com, this is where i look for
games jobs.
