Thanks for the link. I do think your valuation is still very aggressive for something that essentially hasn't launched yet, but I do find your plans for expanding your business via augmenting services interesting - especially the VOIP & sms packages. It's a smart way of profiting off in-person transactions, the most difficult type of transaction to profit from. 
In terms of convincing dealers to use your site, why would they use dealco.in over localbitcoins.com? I think it will be difficult convincing dealers to use your service over localbitcoins, since localbitcoins already has more users (potential purchasers), and is free to use (no monthly fee).
The only incentive I see would be potential volume from marketing. But the number of people who are paranoid enough to require face-to-face meetings for fiat<->BTC transactions is small enough that I'm not sure the volume is there for any provider, be it Dealcoin or someone else. (I'm not saying the paranoid are the only users of localbitcoins, but let's face it - if you're going to buy regularly, and you're not paranoid, it's easier [and faster!] to get an account with an online seller like Gox or what have you than it would be to arrange a face-to-face meeting, drive there, and hope you don't get stood up - or worse, mugged.) I don't see that paradigm changing by any appreciable extent any time soon.In terms of convincing dealers to use your site, why would they use dealco.in over localbitcoins.com?
