About buyers request to see my previous work

[sanapoet]

Hello everyone.
I received a message from a furniture selling site to write description on each of the 100+ categories. We confirmed over the amount and the delivery time then I sent him the offer which he has not yet withdrawn. He has asked me to send my previous works but those I completed previously were for commercial purpose and I’m not sure that their work is complete yet.
So I needed answer to should I or not send him previous works and can I send him link to my instagram account if he asks to see the works done there. Please I need guidance really quick, I need to answer his questions soon without offending him!
