Hello ghost ;)
I can help you with your page.
You forgot to add that you need a login form in order to avoid anyone to be able to post news, I guess you will be the only one posting them.
There are several widgets for editing your posts, so it's just a matter of integrating one of those into your site. The same goes for Discuss and Tumblr.
You don't specify if you want to be able to edit yourself the sidebar, if that's your idea, I will have to review my quote, as it's extra. If you have static links to advertisers, then it's included in my bid.
You also have a "Shop" menu that's not described in here. Will you want to put something in there or you are just planning ahead?
Could you tell me which font have you used for your mock-ups? If I have time I may make you an HTML mock-up so you can see how is going to look.
Have you already bought a domain? Have you contracted hosting? If not, I can help you with that too.
Regarding the "bulk upload" you are asking, I think the best way to organize your comic would be to use folders for that, and make a script that automatically scans the directory in order to deduct the proper categorization. This way you just FTP to your site and upload the images in the proper folders and that's it, no more work involved.
Please tell me what kind of organization do you have in mind for your comic. Just chapters?
If that's all you need I think this is doable in one to two weeks approximately.
Thanks for considering my bid.
