Drew,
You mention that for 10K you would hope that you should get IDX. I'm not so sure that I would set my sights so low. Everyone and their dog offers IDX nowadays. In fact IDX is getting to be passe. What you really want is to combine the general effect of IDX (Searching the MLS) with the visual mapping of Google, Yahoo and others. Then add in the analytics tools that they offer and with a few other little tricks you have a thing that's been around for awhile called "mash-ups".
You'll recognize "mash-ups" from those cool MLS maps that show push pins or balloons at the exact point of the MLS listing. When the cursor is moved over the push pin or balloon, more information such as price and address come up with "More Details" as a further hyperlink to see more details. Get a site with mash-ups for your MLS guide and you'll not know what to do with all the calls . . . as long as you are Driving Prospects to Your Website with SEO (Search Engine Optimization).
So what's the best way to find these tools? I do searches on the Internet for various towns and cities (the larger the better) and specifically look for the top agent's ranking. I don't even look at the major real estate company websites as they have somewhat unlimited funds to spend here. You want to find a real estate agent's website that is using mash-ups and ask them how they put it together. These are in such proliferation now, that the cost is coming way down. It's now getting to be 3rd party stuff that you can pretty much buy off the shelf. But you'll have to talk to your local MLS first to find out if they allow these 3rd party companies to access their data (isn't it ironic that I have to say "their data"?).
It might eat into that 10K budget, but the two best things that you can be investing in right now (especially with the market the way it is) is SEO and mash-ups. SEO to drive prospects to your website, and mash-ups to convert them once they get there. You've got to be seen as the most professional agent to work with.
