Convert PDF documents and return them by email

I have around 55 emails each containing one attachment each, in two different email accounts. I will send these emails to you and I need you to send an email back to the SAME ADDRESS. You need to keep the exact same subject of the emails. About half these attachments are in PDF format and I need you to convert these files to .png files instead (for example using the following Linux software [login to view URL]) .I also need you to convert the names of the attachments so that they no longer contain special characters and no spaces. Please convert the following special characters: æ -> ae, Æ -> Ae, ø -> oe, Ø -> Oe, å -> aa, Å -> Aa. Please remove all other special characters (non alpha-numerics). If you provide an email address, you can have a look at the attachments first. I will accept bids of less than 15$ immediately if you have good rating. Please specify in your bid how much money you want as I always get confused when you write hours.
