Convert 2 projects to 300 DPI ... quickly

Hello, I need someone to convert a 72 DPI file to 300 DPI. It needs to be re-done, not simply converted to 300 DPI. I need this done quickly. I'll provide the PSD files and fonts. The first file is an envelope and the second file is a letterhead. Both files are for print. Please post if you can do the work and post a bid. Don't post a huge resume or I will ignore you. Any questions, let me know! Roch Lambert
