LMDB data store in C++

I need a C++ class that works with LMDB engine to store and search a number of 4 kind of entities indexed by UUID. I will provide the source code for the entity classes, You will deliver the C++ class that will implement CRUD operations for each of these entities in a LMDB store. You will have to use a serialization library to do the serialization of the entities. Also, you need to deliver a small main function to demonstrate the usage of the class. Your code should be compiled with gcc or clang. I need the project by tomorrow. When placing your bid, add a description of how you plan to implement the functionality and a description of what you will be delivering so I can be sure you understand the scope of the project.
