Custom Asterisk Solution

I need an customized Asterisk solution for an event hotline. I want to be able to schedule information once per month and have the system to dynamically create playlists containing audio based on a query. i.e. Users will be able to call in and hear information about events occurring that day or within the next week. Further Details are provided in the attached document. ATTN: * Automated/Generic bids will be ignored * Include references to past asterisk work in bids * if you have questions or need something clarified ask before bidding. * ANY CODER submitting a ridiculously overpriced bids without a sensible explanation for pricing will be ignored * Bid competitively
