Add-on Simple Xenforo Addon Needed

[NickH]

I currently have an API on another site which is used to lookup products, compare the prices and then display them.

I want a Xenforo addon so that I can have 2 things:

1. A searchbox that will simply lookup from my API and display the results within a page on my forum.
2. a bbcode so if I did [compare]ps4 console[/compare] it would lookup and display the cheapest 3 items.

I have a wordpress plugin with the code, and I can provide all of the straight PHP code for the API but I just don't know how to make the addon.

Feel free to let me have rough pricing.
