I'm not sure I understand the question. Are you saying you are an employee of another firm and you have a company on the side that needs a business loan?
Either way, it depends on the state of your business, what you want the loan for, and what assets you are willing to put up. Here's some ideas:
1. Line of credit against inventory or AR. I have no experience with the former, have a lot with the latter. I've used a LOC for AR in many companies including my current one. They are quick, painless, and work pretty well for normal operating issues.
2. SBA Lending - I have used SBA many times in the past. I'm not up on their current plans but in the past they had a "microloan" program for up to $25K that was easy to qualify for. Back then the next step up was up to $100K, and then they had loans over that amount. The problem with SBA lending is that a bank does the lending, the SBA backs it up to a max amount. That means the bank, and the SBA, is typically looking for assets to secure the loan. Last time I had an SBA loan (a long time ago), I secured it with a Condo I owned outright. Point is they look for hard assets to take if you default.
No idea on what current rates are, my CFO does that now
Good luck.
