Seeking SBA Express Loan to acquire a portion of a business

Does anyone know of lenders that provide SBA Express loans up to $500k to acquire a portion of a business?

I’m in the process of acquiring a landscaping business in the northeastern US. They have a 20-year history with their clients. $930k in revenue, and $280k EBITDA.

They’re looking to close in a short timeframe, which is why I think the SBA Express loan would be best option. If anyone knows of any other options I could use, please, feel free to let me know.
