My small company offers a service of grocery shopping and delivery (I shop from the local supermarket) for the handicapped and elderly people in my community.
My problem is that the prices in this local supermarket change everyday, so they not necessarily match my prices online where each item of the supermarket are represented.
So I'll need integration an of a credit card payment solution that allows some sort of 'retaining' option. What I mean by that (not sure if the term 'retainer' is correct) is an option to secure a minimum amount on the credit card, pretty much the same way the car rental companies do it.
The reason I need to do this is because prices in my local supermarket change everyday and I will clearly indicate to the customer that all the prices on my website are just informative and not necessarily current (I'll update them only on a quaterly basis).
In other words, the total amount in the cart on my website when the user checks-out will never be exactly what I will end up charging to his credit card, because I will obviously charge him/her the amount from the supermarket's cash register's receipt after i'm done shopping for him/her.
So this 'retainer' is for me a security, so that I don't show up at the client's home with 300 dollars worth of groceries or more to be delivered, and no one is at the door for reception.
So the balance (plus or minus) will be charged MANUALLY by me on the client's credit card, right after I live the cash register at the supermarket (through a phone authorization I guess), based on the actual receipt from the cash register. I hope this makes sense.
In fact, that doesn't change anything in the Magento website itself, but what I need is a credit card payment gateway that also accepts this type of 'money retainers' and 'manual' transactions thereafter. This is all new to me, and maybe all Payment Gateways accept it now, I don't know, as it is my first ecommerce website.
But if that's not the case, then I need you to advise me on which credit card payment gateway is the most suitable for me (and whose fees are the cheapest), and then install it on my magento website to connect with my cart.
If you have any question, don't hesitate to contact me.
IMPORTANT: YOU NEED TO BE A TRUE EXPERT IN MAGENTO AND PHP (not just a template designer). Please DON'T BID if you don't know how to integrate a payment solution to Magento.

IMPORTANT:>>> The budget here includes the payment gateway set up fee. If you want to bid just for your consultation on which providers I shall use and it's integration, then my budget is around 100 dollars for that.
