Anyone Knows something about Drupla Mapping and Geoproximity Search

Hello TreeHouse:

First I want to congratulate the entire team the tree house for the great work you do and for all the knowledge you share thanks guys!!

After some months I have been trying to put together a development project based on drupal CMS and made ??good progress and I've learned a lot along the way but I've also discovered that I had many gaps in knowledge was so reach tree house

I wanted to see if anyone can advise me what is the project, is a nonprofee project that is found in different parts of the country find and register mexico Recycling Centers and locate on a map and then relate them to the type of item they recycle at each point.

To then make a search by proximity and by Article ie for example in the 03100 postcode recycling aluminum cans and show all available points around this zip code that recycle this type of product

The project is going forward and I can save information centers and their coordinates and I can relate to the type of items that are recycled but there was a bit frustrating not being able to achieve to make the search for Proximity search and combine it with the items I'm really stuck on this

If anyone knows about the topic or who can help or advise me with this so that it can end this would be a little sad to stay so the project is based on a site named http://earth911.com/

And model search is on this page http://search.earth911.com/?utm_source=earth911-headerfooter&utm_medium=secondary-nav&utm_campaign=advanced-search

My Proyect is in http://recic.la/

If you are interested in helping with this project or would like to help me finalize me to contact me right through the forum to give more details of this
