We are a small manufacturing business and we need to expand. How or who can I go to for this help?

We have been in business since Oct 07. Current payables is tied up at customer but is being paid, slightly late. We want to expand in order to diversify product base with purchase of additional equipment to the tune of about 30k. My personal credit is not bad it is just non existant. I have a personal loan that I have not missed a payment on for 3+ years, have 10 more payments left.
How or who can I go to for this help?
Tks, Ed
