All kinds of services can be offered on PPH, however, there are just a few services that are not suitable for the PPH marketplace.
If your Offer has been declined altogether then you should have received an email to the default email address on your PPH account explaining why (always checks your spam folder). Alternatively, take a look at the Offers posting policies to find out why.
If you believe your Offer does meet these policies, or if you can offer another service that is accepted on PPH, then post another Offer and we will take another look.
If you have received a message that your Offer needs some changes made before it can be accepted then find out more here.
