Need open source community help!

Hello everyone- (skip to the *****'s to see the questions if you don't want to read all of this thanks) This might be a little off topic here but I really need some help and a great opionion on this matter. Here's the situation, I have created this software in php and mysql. What it is is it has user authetification, event calendar for several web sites, a personal calendar for each user of the calendar, and a company calendar. I'm hoping that I can get to a point soon to release this under the gpl and have the open source community help develope the software, if they wish. What I'm using this software for... The company I work for only has one developer (me :) ) and they have 6 web sites they want done. So what I have done is created this software so that I can enter all the employee's of the company and then give them access to the sections they need. For example, human resources has access to add new employee's, delete employee's, and update employee's information. The average user has access to a personal calendar in which they can add events give the event a time, a name, and a description. Also, the average user has the ablity to chance certain things about their own profile.. i.e. address, phone #s etc. Now people who I give access can have access to the event calendars for each website and they will be able to add events, delete events, and update events. The options when adding an event is the event name, the category of the event (i.e. concert, on location promo etc), where the event is being held, the person to contact for the event, time of the event, price of the event, the description of the event, and an option to either show the event on the web or not. Also, the admin has the ability to add new "modules" to the software and then give access to whomever he/she see needs access to it. Lastly, there is a huge help file that is generated dynamically when you add these new "modules." (sorry about the lenght of this but it's necessary) Now here's the evil twist of fate... There's a company who has some calendar software that has a TON of features that I don't have in my software (as of yet). However, they are a total Microsoft shop running all their code in VB, ASP, and their DB is MSSQL 7. I really don't like the fact that they use Microsoft because I am going to be the one to administer the box this is going to be running on (would much rather run unix set it up once and leave it alone, unlike Microsoft where you have to babysit the damn thing). Now I've been talking with these people and they pretty much refuse to move any of their code to php, mysql, or any varient of unix because it wouldn't be cost effective to them right now (they said that they might do it later when they can hire a team to convert all the code over to it). Here's the thing.. I've been working on this software for about 4 months now so I really want to use it, but the big guns here in the company want to use this other ASP Microsoft stuff that has a ton more features. If we go with ASP crap, I'm going to have to learn ASP and VB (I'm assuming most DB's are the same so learning MSSQL 7 wouldn't be too hard) and I'm going to have to babysit the Win2k server, which is something else I don't want to do. ***** So with all this said I'm wondering just how welcome you think this software would be in the open source community? Is there a need for something like I have and am still developing? Do you all think that I could get some more developers to work on this software to make it even more powerful than it is now? The reason why I ask these qestions is I don't want to go with Micro$oft, throw away 4 months of work, and have to learn entirely new stuff. Any suggestions or help would be great! Thanks SO much!
