Hi,
I already have this script available, and ready to install on your server. The price is £119, which includes purchase of the script, and 1 hour install/configuration time. Further hours of configuration are billed at £30 per hour. Please get in touch if you would like to see an example of the script running and working on my server (you will have to add a friend on Facebook).
Almost all scripts can be installed quickly and easily in the hour provided in the bid price, I am a Facebook developer for just under 3 years, and am a leading developer in the Facebook community. I can give examples of my previous work, and a link to tutorials I have written on creating Facebook integrated applications.
I will probably not be the cheapest to bid on this project, but if you want your script installed quickly and easily with no problems, then you will get what you pay for.
Thanks for reading.
