Here are the nuts and bolts of the process.
As an example, here is an email I received and my response today.
Good afternoon Bob,
I hope this finds you doing well!
Thanks so much for responding. I am not sure how this process works. What is the process once I submit the photo of the painting? Is there a fee?
Thanks so much in advance!!
Wishing you a great day!!
Hello, Customer X,
There is a fee of $ 100.00 to appraise your painting and issue one of my certificates.
Here is an example : http://126.96.36.199/CERTIFICATE%20OF%20AUTHENTICITY.htm
The value I place on these is for insurance purposes, based upon current "replacement" cost for a similar painting by the same artist. I also inform you of its current liquid value, which generally is approximately half of the appraised value.
If you have a painting that I can use in inventory and you wish to sell it to me, I will refund your fee when we agree to a purchase/sale agreement.
In that case, I would need to physically inspect it or arrange for a trusted associate from your area to do so on my behalf.
If you think that's fair, we can proceed and I will give you my mailing address.
I accept payment only by personal checks or cash, and occasionally Paypal, although I prefer not to.
Please let me know.
