463630 Amending text on png file - Graphics

I have a header which I need the text replacing to my choice, same font size and style but with my words. Should be a simple job for an experienced graphics programmer. The file is attached. The following text needs to be replaced with: From: design. to: you post. From: ideas. to: we advertise. From: usability. to: we filter. From: development. to: you recruit. Also the text at the bottom of the header needs to be changed from: hi there! we are creating smart website To: fill any job for £199 ! (! is on a angle again as original) kick start your recruitment - buy 2 get 1 free. Again same font and colour scheme as the text it is replacing but the "hi there" part to be a smaller font for the new sentence to fit in. I believe the original font is Arial MT Bold or Light?
