Newbie Questions before I Get Started Selling

Hi everyone! I'm getting ready to jump in but haven't posted my gigs yet. I'm a Certified Life Coach with a coaching business. I've read (and re-read) the ToS.
Here are my questions:

1. Can I include a link to my life coaching website anywhere in my content, bio, or in my communications with buyers?

2. In one of my gigs I'd like to ask for a picture of the buyer to send Reiki and provide a "reading" to the buyer. The buyer will have the option to provide a picture. Is this something that might not get approved?

3. I've read in the ToS to not share personal information. It specifically mentions Skype, which I'd like to use for one of my gigs. However, I do see other gigs that offer introductory life coaching using Skype. One was a featured seller.

4. I understand any gig is to be offered exclusively on Fiverr. I'd like to offer an introductory life coaching session as one of my gigs. I do offer an introductory session on my website, as do most coaches, so in that sense it's not exclusive to Fiverr. I do see other life coaches offering introductory sessions on Fiverr, again, one is a featured seller. I'm a bit confused.

Thanks for any help clarifying these questions!
