We have web site allowing book appointments to doctors.
Site looks similar in some way to Z.o.c.D.o.c.
You need to have strong skills in PHP5 with OOP, deep knowledges in MySQL database.
Tasks are about Google Map integration, Schedule, Prices, API integration
with other services as well as simple tasks.
Web site is on Russian, though it should not be a problem if you do not know it.
