Pitching for the first time, i am introvert, candid and blunt

Asking for advice. Its my first time. I am going to incubators and VCs to show/pitch my prototype.<p>One of them whom I am approaching is kind of a new incubator itself, and have promised to help me use their client and will do the sales stuff for me. Is it okay if I mention to them, that I am going to other incubators as well?

I don't have a co-founder and am doing all stuff alone. From equity POV and other challenges, general advice? What not to do?

I don't have any ex in pitching. I have worked hard on documenting and simplifying "what my app does and what it is" (as in x of y, eg. yellow pages of newspapers etc.) Just that, I am not sure of revenue and did not put any imaginary number.

Awaiting Your opinions/advice!
