Cubecart Alexa code insertion and set £0.00 to "call for price"

Looking for a quote to carry out Cubecart Alexa code insertion and set price when at £0.00 to "call for price" we have several cubecart stores and will work with chosen partner on other projects once satisfied. We will give temporary access to our store to enable above work to be completed. Ideally looking to get work done immediately. bidders must be expert at code and ecommerce carts. Payment will only be made upon our satisfaction, which will be when, Alexa certifies our site following their code input, and cart will display "call for price" on any item that we dont input a price for. Please note we have a lot of cubecart projects for right partner.
