I believe my cell phone is in my profile or LinkedIn.

Depending on comps and market value after repairs, I would suggest that if you need to barrow the money from a friend or family member, a fix and flip may be the best situation for you until you build a "nest egg."  

It provides a second line to cell phone for business.It is a Citrix app and it is free.  

It's the what came first the chicken or the egg syndrome.    

Instead give them your card and make sure they have your cell number.

As I'm sure applies with all investors, I would rather use the majority of my nest egg for re-investment but like you said it's your passion so... don't feel guilty for it.

Eggcellent Question!

Well a cell phone bill and a utility bill.  

For my business i personally write off my cell phone, internet, some square footage for my home office and mileage deduction. 

We want to keep the resulting nest egg liquid.
