Stripe integration in our APP

Hi I need a stripe payment page for our app. We currently have a stripe account and accept credit card payments through a third party online booking cloud base system for our business. We have developed our own business app, but need to integrate a Stripe payment page for customers to pay by credit card when booking online and will also he used by our call reps when booking a customer service manually for credit card payments. Currently the system we use through stripe stores the customer information and credit card number so we can add additional charges as required. We would need it to allow for this. Also we would like the page set up so when a call reps takes the order they have 3 choices of payment options, credit card processed through Stripe or invoice sent to the customer they can pay through a Stripe link on the invoice or they could send us a check and we can manually close the invoice and send a receipt and finally a cash option whereby we accept cash on delivery and then send a receipt. Any cash transactions also have an additional cash deposit of $100 which is refunded or deducted from based on additional charges if there are any. It would need to be set up so credit cards can be processed through Stripe both for online Customer orders and call reps who manually input credit card payment orders. Customer who book online only have the credit card payment option, they will not have a invoice or cash payment option, only call reps will have that option for manual order processing. Invoice and cash payment options will not be processed through Strip but they need to be processed in house through the platform and then generate a invoice or a receipt. Is this something you could do? If so could I have a cost estimate and a description how you create this? Thank you
