I have a marketplace website that get people to offer their services. What would be an easy way to provide a way so that buyers can pay with paypal or CC, and seller can receive the money (through us)
Balanced Payments or Stripe
PayPal offers a service that includes all card types and PayPal. There are also numerous other providers in the marketplace depending on if you are using a shopping cart, hosted payment page or international acceptance.
I have been in the electronic payments acceptance space for 20+ years so feel free to reach out.
You will want to choose Bitcoin if you are future thinking. Buttercoin.com is building an infrastructure for institutions that want to get into local and international payments.
