Hi Sir, Your tasks seems very familiar to me. I am Laravel user from Laravel 4 to now and I am very professional with it. Your tasks also seems very responsible to me since other developers will be using my tool creating other systems.
I know my price is a little higher than your budget limit, but have in mind that the required job is really, really responsible and not that easy.
I am ready to take it, but first we should talk detailed but about the tasks you want.
I am Nemanja, graduated computer scientist from Belgrade, specialized in back-end engineering. I am using PHP for a 5 years and Laravel 2 years.
I'll menage milestones right with you after we talk more about the project and tasks.
Wish all the best, Nemanja
