Hi Mark,

Since nobody seems to want to talk to you, thought I'd add a message.

I'm sure you've heard of Google, if not, I'm sure there books on how
to use Google to search now anyway.
I'm thinking that you probably wanted a decent answer from some people
who have expertise in this area, and well, it appears that ain't gonna
happen anytime soon, so I suggest you start searching instead...

Maybe something like this for a start
