Is anyone familiar with a reputable company that offers lines of credit?

I have a growing real estate business in WI. I need to find alternative resources for reserve and working capital. I have been sent offers for lines of credit by companies I have never heard of. Does any know where I can go and research?

i think having money on credit is not the best thing .
u may have a partner
or to invest ur relatives or friends money in ur business with a rate of the gains ( may be in loss to )
i think that’s the best .
