Linked products, Product Attributes and HSBC

Hi,

Bit of a newbie here, so I hope you'll take it easy on me :smile:

I customising Zen cart for a client who only has 3 products at present. The budget is weany and I'd really appreciate your thoughts on the best way to fast track the following:

If product 1 is displayed, then product 2 and 3 are displayed underneath.
If product 2 is displayed then, 1 and 3 are underneath...

Product 3 has 3 size variations - is there a tutorial/article on the best way to set this up.

The client has chosen HSBC as the payment provider - I'm aware of this payment module. Any known issues, or things to watch for with this?

Many thanks in advance,
Tony

This is not even close to any default function or module add on that I have seen and would require custom coding - not for a slim budget
Product 3 has 3 size variations - is there a tutorial/article on the best way to set this up.
