Call Center Lead Distrubution Database platform

I need a lead management/dsitrubution setup. This is to handle my email advertising campaigns and make them efficient to my call centers sales process. So customer would fill out form and the information in that form needs to be posted real time to a lead database that can distribute based on REP BEING LOGGED INTO system. all leads will be put into community pool and based on whoevers fastest to click ACCEPT LEAD will determine who gets that lead. I would need to be able to disposition each lead and be able to store all leads entered into system. Dispositions will be SOLD DNQ DNC INVALID LEAD call back administrator would have to be able to create new users . Once lead is accepted by one rep i need it to dissapear from community pool.
