seo - Schema.org markup for listing of provided services -

i trying improve seo local plumber website. using following elements in contact section:

<div itemscope itemtype="http://schema.org/plumber">    <div itemprop="address" itemscope itemtype="http://schema.org/postaladdress">  <span itemprop="geo" itemscope itemtype="http://schema.org/geocoordinates"> 

i want list services provided. these shown in list , include: boiler services, installation, fix leaking taps etc.

how markup these multiple services?

you can add offercatalog of offers provided services:

<div itemscope itemtype="http://schema.org/plumber">     <span itemprop="name">mr. plumber</span>     <!-- other properties e.g. address -->     <ul itemprop="hasoffercatalog" itemscope itemtype="http://schema.org/offercatalog">         <li itemprop="itemlistelement" itemscope itemtype="http://schema.org/offercatalog">             <span itemprop="name">services offered</span>             <ul itemprop="itemlistelement" itemscope itemtype="http://schema.org/offercatalog">                 <li itemprop="itemlistelement" itemscope itemtype="http://schema.org/offer">                     <div itemprop="itemoffered" itemscope itemtype="http://schema.org/service">                         <span itemprop="name">service 1 name</span>                     </div>                 </li>                 <li itemprop="itemlistelement" itemscope itemtype="http://schema.org/offer">                     <div itemprop="itemoffered" itemscope itemtype="http://schema.org/service">                         <span itemprop="name">service 2 name</span>                     </div>                 </li>             </ul>         </li>     </ul> </div> 

this based on example offercatalog.
