Edit setting and style in service page

Hi,
I need to know which files should I edit to change some settings and style in the service page because:
1) I need to show employee note before the Booking Button and I'd like to change the box color. (att. 1)
2) I need to edit the style of the Additional Services boxes (padding, margin etc.) (att. 2)
3) I need to link the marker map in a blank page because when user came back he is redirect to today and not to the day in which he was booking a service.
4) I need to edit the style of the area in which service is described (att. 3)

Thank you! A.

1) I need to show employee note before the Booking Button and I'd like to change the box color. (att. 1)
-> You can modify it in file:
components > com_osservicesbooking > helpers > calendar.php
<?php
if($employeeDetails->employee_notes != ""){
?>
<Br />
<div class="row-fluid bookingformdiv">
<div class="span12" style="background-color:#F1F1FA;padding:3px;font-size:11px;color:#63648D;">
<?php echo $employeeDetails->employee_notes;?>
</div>
</div>
<?php
}
?>
2) I need to edit the style of the Additional Services boxes (padding, margin etc.) (att. 2)
-> You can modify it in file:
components > com_osservicesbooking > helpers > calendar.php
<?php echo OsAppscheduleDefault::loadExtraFields($sid,$eid);?>
and
components > com_osservicesbooking > classes > default.php
components > com_osservicesbooking > classes > default.html.php

3) I need to link the marker map in a blank page because when user came back he is redirect to today and not to the day in which he was booking a service.
-> You can edit in file
components > com_osservicesbooking > helpers > common.php
function loadVenueInformation
4) I need to edit the style of the area in which service is described (att. 3)

-> You can edit in file
components > com_osservicesbooking > classes > ajax.html.php
function loadEmployeeFrames

Good luck
