Accommodation management. Needs skill with interpretation of someone else's scripts

Hello First of all we look for a team that is used to read, interpret and in case debug and upgrade quickly someone else's PHP scripts. Secondly before bidding please take note of the following conditions: 1 - Once a project starts we are used to have contacts daily with the provider, possibly through video chat/conference once a week. 2 - We can't pay any sum in advance, however 20% of the budget will be put on escrow as guarantee 3 - The program will be tested on the provider's server before delivery to us 4 - In this cooperation the provider must include 6 month of assistance and upgrade on a weekly base; final 20% of the budget will be paid at the end of these 6 month of de-bugging 5 - further 6 month of assistance and upgrade will be negotiated separately The Project. We have to complete and connect TWO sets of scripts: one contains a program to manage reservations and the other is a database with information and pictures of apartments. 1 - the #1 is not exactly a Mysql database but it contains and/or generates a series of file cards, namely - apartments - agencies - request of reservations with clients details, arrival/departure, preference - progressive templates to answer to a request (greetings, offer, confirmation1, definitive confirmation) - calendar and check of availability 2 - The second set of scripts is a Mysql database that contains records of the same apartments with as additional feature, in the face of #1, the possibility to - upload images - search - publish static html pages wherever in a web site this db also has a calendar and the checking of availability. Our need is to integrate the two settlements in a single program (for example to profit of the different functions at present the information about an accommodation has to be filled twice!) Deadline: 3 months Many thanks for your attention we look forward to meet the right team! Patex48
