Citrix Uninstall and Install VBscript

I have a requirement to script the following brief outline: 1) Citrix PS4.5/W2K3 - Uninstall PS 4.5 from legacy farm, this has to be a thorough removal of the product including rollup packs, hotfixes, registry clean, folder deletion etc. Once PS4.5 has been completed removed then to install XenApp 5.0 onto the same OS into a new Citrix farm 2) XenApp 5.0/W2K3 - Uninstall XenApp 5.0 from legacy farm, this has to be a thorough removal of the product including rollup packs, hotfixes, registry clean, folder deletion etc. Once XenApp 5.0 has been completed removed then to re-install XenApp 5.0 onto the same OS into a new Citrix farm 3) XenApp6.5/W2K8R2 - Uninstall XenApp 6.5 from farm, this has to be a thorough removal of the product including rollup packs, hotfixes, registry clean, folder deletion etc. Once XenApp 6.5 has been completed removed then to install XenApp 6.5 onto the same OS into a new Citrix farm At the moment the published applications etc are not a concern, I will require the above to be in one script that can be run against all flavours of Windows and Citrix. Error checking and output files will be required but this will be detailed once the job has been assigned to you. I will need a freelancer who has done this work before and can provide and example of your skills. Ideally you will be able to build your own environment to do your development work within, I will not be able to provide access to a test lab. Assistance will be provided where possible to provide install media. I require the freelancer to be able to provide the code he/she is working on so that I can run this in my test environment and report back any bugs/improvements etc. If interested please contact me detailing relevant project experience, availability throughout the day and weekends (I am based in the UK) hourly rate or fixed price expectations. Happy to discuss further to provide more details as required.
