Hi. My name is Kevin Reese. I am new to freelancer.com, but I have five years experience in Wordpress development working for a small (now defunct due to CEO's retirement) international agency. I am now pursuing other passions (music), but I find this project to be a great cause that I have the skill and passion to help.
I understand that you need to revamp your sermon manager. I want to make clear that I understand the needs exactly. First, you need the ability to add a new "Series" post type. For the Series, you need the ability to add meta data (such as description, durations, etc.) along with custom background images, colors, and highlights for that particular Series' layout. Inside of the Series post type, you need the ability to create "Sermons" under the parent Series. Details inside of the Sermon includes featured image, description, video/audio files, etc. At this point, implementing most of the "Possible Considerations" found at the bottom of the .docx file would not be difficult.
I only have one things that is unclear: some items listed in the .docx file (such as Topics and Books) do not appear to be currently on your website. I would need to further discuss these details (though trivial) to make sure I understand 100% what you are after.
I believe your church is a useful resource for all Christians. I would be honored to work with you to make the best possible delivery system for your important messages based on your needs. Thank you for considering my bid.
