Buddypress Plugin Fix/Upgrade

I had a wordpress plugin developed for me and it was not completed... The plugin is just about done except for a few small things. The plugin is for buddypress... It creates a tab in the buddypress section of my site which is caled digital garage... In this tab there are 2 sections... 1 to add a car to the garage... (this allows the user to upload a car and its info) The other section is the garage... this is where all of your cars are listed... This all works.... I am also using a plugin for events... here the user can select a car from there garage... this then auto populates the form with all of the information... This all works.... The part I need done is.... Right now everyone's cars added to their garage show up with everyone else s cars... for example... So If I look in my garage.... my cars are there (great)... but so are Johnny's cars and Mikes cars... It should only be the persons cars who is logged in.... When I go to the events section... Everyone's cars are listed for me to select to auto populate the form.,,,, This should only show me my cars to choose from.... Im guessing this shouldn't be that hard for someone who knows what they are doing... Maybe a user id can be attached to the listing... or maybe it already is? and then have a condition to show only the logged in persons cars.... Please let me know what you think??? I will pay when I see it work. I just dealt with someone on this site who took the money and ran... :( I need this completed fast... and not expensive as I am now over budget. I hope to find an experienced programmer that can get this done for me. Send your bid, message me with any questions.
