Tour Op ATOL changes

We are looking for a new developer to work with us as and when required. We have an extensive system written in both ASP and .NET and so it is essential that you have BOTH skill sets not one or the other. Please do not bid if you are just ASP or just .NET Initially we have four small fixes to work on in the existing system. This will help with familiarisation of the system as well. 1. To get us back to being PCI DSS compliant. We have a cross site scripting vulnerability on two pages that require fixing. Both pages are in ASP. Security Metrics who test our site say "Description: Cross-site scripting vulnerability in a parameter to /[login to view URL] Severity: Area of Concern Impact: A malicious web site could cause arbitrary commands to run on a client through a specially crafted link to the vulnerable server. In some cases, this could result in the compromise of the client's cookies, leading to unauthorized access to web applications. Resolution Cross-site scripting can be fixed either by creating a customized error page which does not display the URI or applying one of the following fixes....." 2. To change a display criteria (3 different areas of the same page) when a booking is made 3. To change the pdf that is issued when a booking is made to be in line with the changes in 2 above - we use the Persits Persits ASPPDF tool already, so familiarity with this tool would be useful 4. To integrate a new pdf to be issued by email when a certain type of booking is made (email is already sent just needs the new pdf to be attached to it when a certain type of booking is made - note the pdf needs to be created individually for each booking and stored as there are certain fields that need to be populated - we use the Persits Persits ASPPDF tool already, so familiarity with this tool would be useful) We are aware that the above will require some time to be spent familiarising yourself with our existing system and so please allow for this in your quote. The existing system is large and complex. We are looking for a company to work with on an ongoing basis and so we are looking for you to quote on a fixed price for the above and then an hourly rate for ongoing work We have a specification for the first part of the ongoing work and we imagine that this will be something of the order of $1500 to start but will be constant as changes occur, hence we are looking for an hourly rate. Please detail in your quote 1. Fixed price for items 1 to 4 2. Hourly rate for ongoing work
