How to get my S Corp Lines of Credit?

[Francisco Garcia Jr]

I would like to build the credit of  my company under its own Tax ID. My company was started back in  late 2007 and at that time I had some Investments with partners in Real Estate. Well as you know the crash happened and having partners was not a good idea at that time. My credit has been fixed from my mess back then and is clean with 1 trade line as I rebuild my own personal credit too. But I am more interested in building my companies credit, no issues but no credit either since 2007, recently approved $2k gas credit card for my company, which is a start. So how should I proceed to get unsecured lines of credit? I went the Finance Store, which they charge a % if they get you a loan, I was denied because I only had 1 trade line under my credit, Im still rebuilding it, but its clean and in the 700s
