Cherry Red Records Combined Counties League Premier Division club Bedfont Sports have signed highly-rated midfielder Jack from neighbours Hanworth Villa.
Manager Paul Johnson has long been a big admirer of the midfielder and he has managed to secure his services after seeing off a number of league rivals for his signature.
Mills was a professional at SkyBet Championship side Reading and was also an England under-19 international.
More recently he has played for Wealdstone, Hayes & Yeading United and Staines Town before arriving at Hanworth Villa this season where he has proven to be one of the best players in the league.
Mills becomes Sports` second high-profile signing in a matter of days, having snapped up Addison Garnett following his release by League Two Crawley Town.
