Events without choosing a Starttime and Endtime


Job Description

Important: I just put any amount in the budget cause you have to tell me what you would ask for this job.

I would like to use the Event with the option if I want to use a date and if I want to use a time. Because I have some trainings to offer which are open for everyone and running without any specified date or/and time.

More explanations:
I have a phpfox site running. There is a module called EVENT (all is programmed in php). I need that event customized, so that there is an option to choose if I want to create an event without specifiying a start time and endtime, an event without a date (but if I want I should be able to specify a time). So that event would be visible all the time and never hide.

And what would be the cost and how fast could it be solved?
