Friend and sister surrogates
Tell your family and friends that you need to find a surrogate and consider any social gathering as an opportunity to share the word that you need a surrogate. When using your social network, word of mouth is the key.
Using your social network to find a surrogate or IP is an uncertain process, as it might take more time than an agency-managed journey.
It is likely that you will encounter many unsuccessful leads and this method is harder for IPs with smaller groups of family and friends.
