Custom Wordpress Function (Taxonomies)

Am looking for an accomplished programmer that can modify and write a custom php function for a Wordpress theme. I currently have a number of Custom Post Types (CPT) set up for this website and wish to use the posts of one CPT as taxonomies for another CPT. Currently I have got the script working so that when a new post is added to CPT A it becomes a Taxonomy for CPT B, however I am hoping for increased functionality to this. Here is what I would like it to do: Any newly created post of CPT A becomes a Taxonomy of CPT B Any newly created Taxonomy of CPT B becomes a post of CPT A When a post is deleted from CPT A it is deleted as a Taxonomy of CPT B When a taxonomy of CPT B is deleted it is deleted as a post of CPT A This also needs to work for sending posts to the trash and then restoring them back to the CPT. Please note that I don't want to use any existing plugins for this. I have coded the site myself to this point and wish to keep the site as clean as possible, which means the use of as few plugins as possible. Although this is only a small project, I am hoping to find a reliable developer who will be able to work on other areas of this site alongside myself and will eventually require the skills of someone who is capable of setting up a Wordpress Multisite environment. If you have any questions please feel free to contact me via PM and I will respond as soon as I can. Thanks!
