changes to idocscript

I recently purchased the [login to view URL] document sharing script and i need some minor changes to it The changes required are; - create and change logo and caption - create image files for each category. They used image file for category isting. I need one created for each of the categories created - reduce the font size of the category listing (I.e the fonts in brown). This also includes headings of recently added documents, popular documents and others". - reduce font size of document title under documents page so that more text can show - change default memeber avatar image - link google adsense account to all the advertisement places so that google adsense image adverts can show in all the advert locations. See admin panel too. - remove the country flags at the top of the page - remove the "powered by idocscript" at the bottom of the page. A license for this has been bought. The demo of the script can be seen by going to [login to view URL] Kindly check and let me know if you can do this, how quickly and how much this will cost to do
