Thanks Guys... Wasn't too keen about putting a ladder on a ski boat, but pretty happy with how it turned out.
I ordered the two Teak supports from:
http://stores.ebay.com/teakhutonline/
Less than $30 delivered to my house. I emailed the owner and had everything cut to my specifications. He sent me a PayPal invoice. All I had to do was drill some holes and screw them to the bottom of the platform and put teak oil on them.
I got the stainless retractable ladder from iBoats:

Picked up 6 stainless bolts, nuts and washers at the local hardware.
Less than $160 in the whole deal...
