Drupal Entityform validation and theming

First of all:

- automated or generic proposals without a real analisys will be ignored

- the proposed budget is not binding. I will consider your requests if they are justified

I have an accreditation form made with Entityforms module.

A user can insert a certain number of field-collection items.

Field collection fields are:

- First name (text)

- Last name (text)

- Notes (text)

- Days (checkbox multiselect) <- THIS IS THE PROBLEM

I would like:

1) (the easy part) style the form, either via CSS or [login to view URL], so that it looks a little bit less messy.

Check the attached images to see the form now and a possible acceptable layout.

2) (the tough part, at least for me) validate the form (or the field-collection) to limit the number of checked checkboxes in the field collection per role or per user (for example: admin= unlimited, school= 30, agency=20)


- The user can add names (field collection items).

- for every name added the user must check one or more checkboxes (day of visit)

- the user (or role) has a daily accreditations limit, so he can check any of the 4 checkboxes up to that limit

- when the user reaches its limit for a day we can:

1) disable or hide the checkbox corresponding to that day, with an error message like "you have reached your daily limit for {DAY} (probably best solution if doable) or

2) validate the form on submit and refuse submission with an errror message like "you have a {number-allowed} accreditations limit for {DAY} and you asked for {number-requested}. Please correct the error". (This is far less elegant but effective anyway).

3) ANY other approach is OK, including a different form solution o whatever you can imagine in Drupal 7, but must work and be documented. Please keep in mind that I need to build Views and Views Exports with filters from the submissions results and that's why I'm abandoning the webform module with matrix component.
