162369 php scripter needed urgently

Need script, probably in php, where clients would be able to book dates in a monthly calendar, see total cost per order. Possibly integrated payment through PayPal, but not necessary. If you need inspiration, look at: hotels/c0m, booking/c0m, etc. Will only consider bidders who has more than 50 projects in SL history. (Too many others have failed when it comes to the simple scripting for booking dates, so I am not taking risks now.)
