Ask HN: Replace trial with a schedule a call form instead?

so I decided that self service type of customers are really bad for my product and that the high touch clients who I can have a phone chat with and demo them the product has worked the best for me.

Currently I have a 30-day trial (w/o CC number) setup but for high touch clients this is almost unnecessary since I usually close them on the first phone call after demoing the product and demonstrating value.

The people that won't talk to me on the phone, usually ask for a huge discount, request ridiculous things so I am thinking of getting rid of the trial altogether as they appear to be the wrong market fit.

What can I replace the free trial with?

I am thinking of creating a form that will ask their phone number. In overwhelming amount of cases, someone who doesn't provide a phone number usually isn't very serious about buying or is not the right target. However, I am aware that some people might not want to input their phone number.

I am also thinking of doing an overhaul of the landing page. Currently it is sort of like a 'here is the software, here are the features, you connect the dots'. Of course when they speak on the phone, they realize the value but I have nagging feeling that my landing page isn't giving a value perception.

What do you guys think, is this a good approach to take? I'm just cautious because I see lot of SaaS out there seems self serviced (mine is data mining from video files).
