Require someone with UPS API Experience to build a website

I need someone to build my website. Design is already coded. I'm a UPS reseller and am looking to build a website with the following functions PROJECT SCOPE A website where customers can enter their shipping details, checkout with stripe, and receive a shipping label/customs Front end design will be done and coded by someone else. We only need to integrate it. This is the flow: 1) Customer can check sample price of shipping on homepage by entering the following information Shipping Postal code from and to, Dimensions of package, and weight If Postal code is 5 digits country is automatically United States. If its 6 digits it is automatically Canada Info will get sent to UPS api and disocunt pricing info will come back. I want customer to see original pricing and discount pricing. This information will not be saved to DB. 2) If Customer decides to order he/she will click ship now from home page which will forward them to shipping page In this page shipping information is recorded Fields for shipping from: Name: Address: Province: Postal Code: Phone Number: Email Address: Fields for shipping to: Name: Address: Province/State: Postal/Zip Code: Country: (automatic if 5 digits United states, 6 digits Canada) Select if residential or business Customer will then enter the LxWxH of package (inch or cm) then weight (lb or KG) Competitor example: [login to view URL] This information will get save to the database and then sent to the UPS API UPS API Will come back pack with discount pricing I want customer to be able to see discount price and original price. Then customer will checkout with stripe. Once stripe confirms checkout is complete by API information get sent to UPS API and a shipping label is produced. This label will be sent by email to the customer and also displayed on the website for them to Print. Also if the order is international (Canada to the US) the customer will be required to enter more details for customs: This is how the customs invoice will look like [login to view URL] All the information is prefilled from previously entered infromation except the following Item Description, ORIGIN, Quantity, Unit Price, Total This info will be saved to the DB and emailed to the customer as well. I need to be able to see previous customers order through backend with unique ID number which will be provided to each customer or by search their name. Thank you.
