dotloop and api -- 3

I am in need of a programmer who is familiar with the real estate software program "Dotloop". I need to have our listing documents integrated with with Dotloop through their API. Our listing documentation is 18 pages of PDF's, 10 of which will need to have an electronic signature or initial attached via Dotloop. If you have not dealt with Dotloop please do not respond, I need someone who knows. Thanks
