Novice needs assistant with payment gateway integration

Hi everyone,

I'm new to the forums and OpenCart. I only just installed it today and am trying to learn it quickly because a new client of mine wants an online store, and I've never made one before - I'm used to static xhtml/css websites. OpenCart came recommended because of it's ease of use so here I am!

First hurdle I'm trying to get over is the integration of a merchant facility. My client currently already has a site (I'm simply redesigning it) and she already has payments going through Bendigo bank. When I go into admin > extensions to change payment options, I don't see an appropriate choice for this. There is PayPal and the rest of it, but nothing that say's 'merchant facility' or something along those lines.

I noticed on my clients current site that when I go to buy something it takes me to a bendigo site that starts with "migs.", so I searched for MIGS in the available modules and there was one for about $50 - is this what I need to get to make this happen? Or do I have to contact bendigo bank about it?

Thanks for any assistance!

Regards,

Ben
