I need some help with E-commerce

General information for the website: We are an online college
Kind of development: Customization of existing website
Description of requirements/features: Summary:
- The college website is built on WIX
- I have a merchant account with Eway
- I need an e-commerce solution that can facilitate 1-time payments and recurring monthly payments
- Will only process 5-10 transaction per month so looking for free / cheap e-commerce solution

Since the WIX e-commerce store cannot work with Eway, I'm happy for customers to be redirected to another secure payment page to perform the transactions and then directed back to the college's website once the transaction is done.

I don't need you to do everything, just spend 60min - 90min hours with me on skype and point me in the right direction.

If you can help, I look forward to speaking with you.
Samuel
Payment methods: Credit Card, Specific Payment Gateway
