Building a Messenger BOT

We represent a home inspection company called [login to view URL] which targets the South African market. They have eight different services which they sell. I want to promote each of these services via Facebook and allow them to integrate with Messenger to allow them to choose the best product for their service. HouseCheck targets 1. Homeowners who may want to save electricity costs or to have their electrical hot water geyser checked out. 2. Buyers of property who may want to get an expert opinion on their property before committing to a purchase. 3. Sellers of a property who may want to fully declare the serious defects that their property may or may not have to make it easier to sell. 4. Estate agents or realtors who want to promote transparency in deals or to release themselves from come backs or estate agents who have a large rental property portfolio who want HouseCheck to document the condition of a property yeah time a tenant moves in or out. I want to embed links to this chat bot on our website, include it in the emails we regularly send out to these interest groups and also to embed them in Facebook ads we create and promote and get a response. I am unsure if an commerce platform is currently available in Sout Africa yet but that may be a nice finish as well. HouseCheck offers a content marketing strategy and part of this involves giving away three eBooks in PDF format called The South african Home Buyer, The eight most common problems experienced in a home and A builders guide. These are offered to build credibility and to hook buyers into a autoresponder email journey at the moment. A succesful submission would probably include suggestions on how these can be integrated into the messenger app Virtual intelligence. Please indicate overall cost estimates in your proposal.
