Customize Joomla Component - Only today feasible

Hello Twago Coders, i do this announcement here, because i need sombody who can do this today. I need the customisation for my Joomla component today. The CMS Version is Joomla 2.5.6 The component is called "Diginix Content Generation" i need in this component one field more. But its a Joomla standard (default) field and its already in Joomla available. The field what i need is called "external reference" you can see it in each article in meta section (last field). I think for a coder its not much work to add one field to my component, but if i am wrong, let me know! The second thing what i need is that the component output for me after i have create the articles the ID from each article with the input from the new field. The Format should appears like this: 78=43.074781,-79.072037 79=33.074781,-50.072036 80=80.074781,-45.072035 The first before the equal is the article ID and the last are the coordinates what i write in the new field, what your create for the Component..I f you have questions, i am able to answer in some minutes. >>>>>>But remember, i need this customisation ONLY for TODAY! <<<<< PS: Sorry for my english, i hope you will understand all requirements and functions, if not ask me, please. best regards
