Where To Find Reasonable Publishers

I've spent the last three years working in a digital marketing agency, where I've learned a lot from my colleagues. I've been working on an autobiography for several years and it's almost completed. Friend of mine suggested me for this network which will help me finding a book publisher who will publish my work at a competitive rate. I've always wanted to assist others and be inspired by others to fulfil my goals. Any suggestions you have would be much appreciated!
