Planning a Crusade...What are my Options?

"The boss" has arrived...

...in the form of the High Marshal Helbrecht model that I snagged off ebay.

Definitely not the model I got off ebay!

So now the question is, I am too impatient to wait to build up my army, so what kind of Black Templars fighting force can I put together? I thought I would ask the question to you, the experts, for your opinions.

Challenges?

1. I don't have any of the new SM: Codex models. (e.g. Centurions)

2. Everything I have collected to date fits in with the "Old" codex in terms of units and vehicles. e.g. I don't have any older  "regular" Space Marine units that can now be taken with Black Templars (Thunderfire Cannons, Flyers etc.)

3. I don't want to spend much more money - so if you build an army with the units listed below, but want to recommend a unit or two I don't have, please keep it at a unit or two!

Here is a list of the models I currently have (you can see most of them here, although the High Marshal didn't arrive in time for the family photo!) I have added links to photos that might help, but the photos weren't taken with grouping models together, so they are a bit mixed up.

I'm looking for a fun (fluffy, but with a chance of putting out some hurt) 1850-2000 point force to be used with friends, (so proxying is OK, and so is WYSIWIG)
