Add post by simple form

Hi guys,

Not sure whether to post this here or in hacks, but I’m trying here.

I’m working on a project with a friend and he’s going to be adding content in exactly the same way for 99% of all posts.

I’d like to make it really easy and have a form he can use, that structures the post in the same way every time.

So, an example:

Name of post: [field]
Details: [field]

Amount of items: [dropdown-box with 1, 2, 3, 4 and perhaps custom]
--
Item 1 title: [field]
Specs 1: [field] Specs 2: [field] Specs 3: [field]

Item 2 title: [field]
Specs 1: [field] Specs 2: [field] Specs 3: [field]

(Item 3 here if applicable)
--

Pictures: [Easy system for adding one or many pictures]
Show picture [Picker for which pictures should be shown as post image]

– And a few other things, but I hope you get the picture!

So to recap:
1. The user opens the form, fills in all the details requested above
2. When the form is submitted, it is converted into a blog post with a predefined structure

If you have any questions to the above, please do ask me.
I don’t mind getting my hands dirty with some custom coding, by the way. I’m quite technical but just haven’t found a simple logical solution for this yet ??
