For Q1.
You should probably contact your bank first. They will put you in touch with companies they deal with for credit cards. What happens is you provide a business plan, and lots of details about you business and then they will provide you with a special piece of software, for accepting cards. You get charged on every transaction made, and you will have to make an upfront payment for the software and probably signing on to their service.
For Q2.
Do what most of those businesses do to maintain high positions, buy you place.
