Theatre Programme designed for charity production - URGENT!

I need a theatre programme designed and laid out and COMPLETED WITHIN A DAY OR TWO (maybe three). The programme will be used for a large scale youth theatre production being produced for charity. I already have layered .PSD and layered TIFF files of the artwork used for flyer / poster which should provide most of the design elements to use for backgrounds etc. and hopefully save a lot of time (it will need very few amends and that will be the front cover sorted). It will just require copy (I will send), photos, adverts (all supplied ready to drop in) etc to be laid out / designed.

Unsure whether to list this as a 'medium' or 'large' project so please quote accordingly. Thanks.

Finished size is A5 portrait. Pages are flexible but I would imagine around 20 sides (5 sheets of folded A4) including the cover.

Finished file should be provided in print ready PDF as well as .PSD in order that we are able to make last minute amends should this be necessary.

If you need any more info please do feel free to ask but I have tried to cover everything you may need to know in advance here owing to the extremely tight deadline!

Thanks so much for looking. I hope to hear from you soon.
