Travis,

Try IDX Broker. They do not  host the agent's website!  They host the IDX  on their website, so that it looks like it is part of your website.  They are one of the best in our opinion. We use it for our clients as an additional IDX to our own proprietary version.  Our web developer hosts our clients sites on his server through one of the best hosting companies.  He creates our sites on Word Press.    I hope this helps and I did not confuse you.  A

Have your client sign up for IDX Broker: 

THen you can create all the pages for the different keywords he wants to rank for. 

I have a WordPress site with IDX broker but it is not hosted by IDX Broker.  Ron and Alexandra Seigel 's answer is the same as mine. 

Katerina Gasset could give you guidance with that....

What Katerina Gasset said.

You should know enough to do your own research on this.

Jonathan Denwood he's a WP expert designer!

Many of them out there, contact someone like Katerina Gasset for the top expert advice in these matters.

Katerina Gasset can help with this.

There are quite a few IDX wordpress plugins out there (IDX Broker comes to mind first) that allow you to have an IDX with registration options on your site.  They host the data, you host the site.

Ron and Alexandra Seigel and Katerina Gasset nailed this one!

Try IDX broker.

Yes a monthly fee. First, really figure out what you need before you get ripped off. In my MLS we can 'buy' a direct feed from them BUT .... do you know what to do with it once you get it?

I get not so hire someone. I have many selections & will be back.

If the agent's MLS is FLEX, they have a WordPress plgin that I like. Or they offer API to developers.

I think you can 'cook up' a solution with the suggestions offered and serching for WordPress plugins that will prove useful.

Travis, seems you are having many hats. Can you cook too?

it's a separate fee but not required to host.  Several IDX vendors out there.

There are several options for IDX but, yes, you will have to pay separately for that - or have the agent that you're building the site for, pay it.

There are many out there in Internetland. Google and read the reviews.

You have some good answers.

travis klein you received very good suggestions. Good Luck.

My suggestion: if you don't know how to do it, you're probably not the right person to do it.

Think you already have some great advice!

I would find someine who is versed in that area.

Great answers are here.

So many good answers here

IDX broker has the best plug in for wordpress. Also ihomefinder.com

There are monthly fees associated, but I think you pick your plan.

I have a long response, but you have to be kidding.

I have heard IDX Broker is the key.

No.
