Require the design of a "freelancer-type advertisement script".

Am in need of a competent freelancer to help with the design of a "freelancer type" script which is intended to specifically serve the African community and promote freelance work as a means of buffering the economic downtime in the conventional job sector. The developed script should allow customization such that new payment details can be added as well as SMS alerts. Hope to speak to someone qualified soon. Regards, Wisdom Enang
