Create custom login form, form to add k2 item with additional fields

I require a developer who is proficient in Joomla 2.5 & K2. I require the following: *a custom new user form created which will allow users to enter 4 additional data items and store this information into the user profile. *a custom form for the user to add items to the K2 database on the website front-end ie. not the standard k2 add items form but a form created using a module or component which connects to the k2 database and allows admin edits in the back-end *the item added to the database when published by admin and displayed on the website front end, must display the details entered by the user plus the additional 4 data items added when the new user signed up.
