Php / Mysql / Wordpress professional needed

Hello, First of all I wan't to say that: 1. If you are not Php / Mysql / Wordpress professional just don't write me at all. 2. I need this to be done asap, but I'll be able to pay on 10th September, so if this term is not ok for you also don't write me at all. I have 3 task: 1. I have plugin Userpro, something bad happened and user's can't see other users' profiles, it's database issue. 2. Write me laptop to prove that you read description. 3. I want to add functionality like this: every user must have booking times (15 minutes difference), user must be able to book other user's time, if other user will approve the time will be booked and other user wont be able to request to book same time. 4. On member's page there is a search by username, I want it to be changed to search by name or surname, not by username. Please keep in mind that budget is small, but I'll provide much more and much better jobs in the future, and if this work goes well, next time chosen programmer will be approved automatically.
