"I'm an amateur scifi writer with a severe case of writer's block, but some good ideas. I need all the help I can get if I'm going ever get any of it finished, much less published."
Word of advice about "writer's block". Ignore it and write. Let it come out lame. Let it suck to high heaven. You can always rewrite bad work, but you can't rewrite nothing. That should be the least of our worries.
When you write on a schedule, there's no such thing as writer's block. It's not allowed to exist. When it's time to write, it's time to bloody well write, and you put words on the page.
It doesn't matter if it's not your best work. That's what drafts are for.
