Need an album produced and some guidance

We're a sibling band, looking to put out an album. We've never released anything before and don;t have much experience in the music industry. However, we have written, and produced (pre-produced?) and practised many songs. In total, somewhere near 500+ songs. We need a little help in finding our sound for our first album, and then getting maybe something like 5 songs produced. Mastering we'll do it seperately. Thanks!!!!

Additional info:
I have a song already recorded and want some additional production elements - sound effects, synths, samples, percussion, re-recorded instruments. I will be recording vocals on my own. I'd like to work with a top pro who's worked on hit songs and I have the budget for that. I'm looking for someone to re-record a demo I've already created, but with high-quality samples, synths, and effects. . I'll hire a different pro mixer and mastering engineer, for the moment I'm just interested in production. I'm an indie artist. I need some help with songwriting as well. I don't have a hard deadline for this.
