Build a Wordpress plugin

We are looking to build a plugin for our wordpress website We considered using a Wordpress Catalog plugin, but can’t find anything to fit our needs. The catalog plugin would work, but it need to be customized so that users have their own catalog when they login It’s possible that this could just be a hack of a current plugin, or it might have to be completely redone. We would need to talk for you to let us know your process and to decide what you think will work best for this. We need this to be done urgently We only select programmers who are serious and give preference to individual programmers rather than companies Max Budget is 100$ (inclusive Freelancer charges) Lowest bid wins Bids higher than 100$ wont be considered so as Copy and paste bid.. Your bid must explain the solution I need
