Help - Options to create a sports photo collage?

[xjben]

I have a dozen softball photos (grand slam series with the batter hitting, running, team congratulations) that I would like to turn into some sort of collage. What are the options to do this? Online sites I should check out? Templates I can get? I haven't tried doing it manually in Photoshop...might do that, but I'm thinking there might be an automated template/option out there I could use. Any recommendations on the collage creation?

Also - if you have a recommendation on pricing, would love that too. Maybe a reco'd price for several size prints of the collage, like 11x14, 16x20, and 20x30 prices? I've compared lots of other print prices, but not much on the collages before. Thanks!!!
