I do! https://soundcloud.com/shaun-finnegan
Just bear in mind I haven't added anything to this SC in a little while. Lots of old game stuff I did on there, and I have actually done some very basic SFX for games as well, though mostly digitally created. Depending on how many sounds you need I might be able to do that.
Per your 2nd question: images are best (concept art, screenshots) an overview of the game (you can dm me or email consolomusic@gmail.com), and we can have some back-and-forth about the tone/structure and also what style of music you'd like to have in it.
