7 mil one piece, front zip - anyone make them?

I am 59 years old and agree with the arguments for ease of getting in and out of wetsuits. I need a one piece (farmer johns are OK, but I have to add way too many weights) - front zip, 7 mil, with zippers on the writs and ankles. Where in the world can I find one like this? My friends are buying back-zips with no ankle/wrist zips - and are paying a fortune to have them modified. Help!
