Directory Press Customization

I have a website which I have installed the Directory Press template ([login to view URL] ) but would like to add some features that I would like to get estimates for. Please tell me if you have experience working with directory press, and send at least one relevant example. It would also be great if you could give me cost estimates for each of the features I would like added to the site. thanks! New Features: In the "Submission" Tab of DirectoryPress: 1- Add a field for "events" which allows users to select more than one from a list of options 1a - Allow users to add an event to the list of options 1b - Add "event" as a search field 1c - The events will also have "listings" in the directory, so it would be great if there was a way to somehow link the "event" field with the event listings (for example If my listing says that I participated in CelebrationX , CelebrationY, and CelebrationZ then it would be great if those could be linked to Listing pages for CelebrationX , CelebrationY, and CelebrationZ and similarly if there was a way on those event listing pages for there to be links to the listings that are associated with them) 2- Add a feature where someone can have their existing website in an iframe on their profile simply by entering in the url (for certain member packages only) 3 - Have uploading a picture as an option on the "add listing" page 3a - Have a default picture (which we already have) automatically assigned to a listing if a unique image isn't uploaded
