Giftwrap plugin

-- url of the page with the problem -- : www.polyspiraldev.co.uk/jhjoomla/
-- HikaShop version -- : 2.1.3
-- Joomla version -- : 2.5.28

I need a plugin for giftwrap to be added that will be charged at £4.
So that on checkout there is a field for the personal note, and once filled in it adds the giftwrap to basket and charges for it.
Small budget as this is a fix from an old version that has broken.

Hello,

We are interested and available. Please contact me at sanjay[at]deligence.com and do let me know your budget. Also do let me know about the code that was already there. Which version of Joomla and HikaShop were compatible with that code and can I access the code now?
