I’m trying to see if this is possible using custom post types. Basically
There are 4 custom post types:
1)the “Forms post type” holds 3 forms;
ii)[bid for items]
iii)[request for bid]
2)the “companies post type” holds the entries submitted from the form [register company] which will serve as each companies “profile page” with restriction to only their page.
3)the “items post type” is where items are created and can be added to the [bid for items] form
4)bid “evaluation post type” holds the entries from the [bid for items] form
I’m a wordpress novice but i feel with the power of CPT and metaboxes this is possible.
