IDX/MLS Plugin

Hello,

I have been searching everywhere for days trying to figure out how to create my own MLS/IDX Plugin. I did find a few good topics on how to create a Plugin, and it is something that I had no problem doing.

But my main issue is how to create that plugin for the purpose of being a Property Search Feature that utilizes MLS/IDX.

I have a precise idea in my mind, the design and so on, and I want to be able to make it to my specifications with the abilities to search through http://www.realtor.ca and gain all the information necessary.

I also do not want to simply purchase any random Plugin, because they are not at all designed the way I want. I made the mistake of purchasing a Theme and had to spend weeks going through the Functions.php and the Style.css to make it anywhere near what I wanted. Had I of thought of just making my own theme, I would of spent the same amount of time and got better results.

So that was meant to clear the air for anyone who suggested to buy a plugin.

Now, would anyone be able to provide any help on this topic of creating my own IDX/MLS “Property Search” Featured Plugin?

Thanks!
