Comprehensive Review of Conference Call Services

I need to have a comprehensive detailed review of all major conference call services. This will include 1-800 services, flat fee services, pay per minute services, pay per users services, family-friendly services, corporate services and any possible combinations of above. Services that cover only USA, services that allow connection between internations callers, such as between india, north america and europe. Services that include calls form Asia, Iran, or other remote locations would be nice to include. I need to have a comparison review of 30 major conference call service providers, their "pros" and "cons", separate breakdowns of their pricing structure (signup fee, daily/monthly/yearly fees, per minute, per legs, per call, or whatever else fee...). I need comprehensive comparison of their pricing structure, plans, subscriptions. If any of them have any outstanding offers - I need details and mentioning of this as well. ## Deliverables The review should be nicely formatted as HTML document and be ready for presentation. The total size of the material should be about 10 page HTML document. I encourage Coder to split the review in multiple documents. No other additional corrections, adjustments, and reformatting should be required. Review should have about 2 page introduction that generally compares today's conference call services without mentioning of brands and names, detailing general advantages and disadvantages of them. The remaining 8-10 pages would be more specific, mentioning names of services, their web sites, brand names, prices, options, offers, and other specific details applicable to each. 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
