Unit Test of SmartContract

Hi, I'm looking for someone who can unit test a smart contract with framework truffle in javascript. The smart contract in question contains several lines of code, but specifically I have to test only some of these (we are talking about about 100/150 lines of code written in solidity). The smart contract refers to a DApp where there are people who vote for the validity of a project to be 3D printed and if the majority of voters are successful, they will receive a reward made available by those who announce the project. by betting a quantity of tokens (ERC20 token created on purpose). What needs to be tested is that the functions containing the token transfer work. We will discuss further details with those interested in this work.
