Either way, there are many investors out there who would consider SAAS services, india is a hot market right now actually even for those of us here in the United States.

There are several marketing agencies doing just that right now. An ERP could be used for various processes so that gives you advantage in 'qualifying' potential investors in makerting, SaaS, HR, sales CMS, etc... Investors can be other founders of successful companies who are involved in your industries... Aim to connect with those who would benefit from your success and not see you as a threat at some scale.

You can also go on Quora and ask for leads there, many investors are involved there and some have even given out their contacts there. Angelist is another although you'll be lost within that community because of the size of users, but it does help!
You can also take the most direct approach: look for a current larger business that operates in an industry that you can add value to but don't compete for and offer the company an opportunity to own stake of your market offerings. Consider a cell phone service merging or acquiring a cable company. You might look for a company could in the future benefit from acquiring you completely- but approach them offering only minimal stake. You get your funding that way as well as gain a marketing partner and market share, not to mention the potential of future full acquisition.
