Ultimately depends on lots of things:
- How much you want the position
- What the company expects to pay
- What others applying for the position might ask for
- How much you need to get by
- How much you would really like to get paid
- How you would stack up against other candidates

Your best bet is to get a good sense for what's a likely target range for that particular role, weigh your desire for the job and how strong a candidate you'd be, and pick a value within that range.

I don't know enough about the position to have a good sense for the range, and I wasn't able to match your description to one of their listed positions to get a bette sense. I'd probably just end up looking at salary sites anyway, which you can do on your own.

It really depends on what the individual employer is looking for. There will be outsourcers who are happy to do this for minimum wage. But will you be happy with that?

$15/hr is the minimum I recommend for freelancing sales opportunities. If you're doing outbound calling, more. I've charged $30/hr freelancing through sites. But I have expertise that makes me more valuable than that; they know they're getting an amazing deal. And I won't call for just anybody.

If it was tech support alone, ie. no selling, then the hourly rate might be lower as the calls are inbound and there isn't any selling. Maybe $10 or $12.

Look at the value you're creating for the client. What is a sale worth to them? How many do you think you'll be making a month? Multiply those numbers together. This is the total monthly revenue you bring in. You want at least 10% of that; work back to your hourly rate from it. Now here's the acid test: if the hourly rate is too low for you, you know the opportunity doesn't have enough money in it to be worth your time. Make sense?

Since this opportunity was two months ago, I'm sure it has long passed. However, I wanted to provide an answer for people in the future who have a similar question.

Don't ask for an hourly rate. We all hate the people in our lives who charge us 'per hour'.

Be creative. Tell your employer that you'll take a monthly retainer to be available 24/7 to provide all the support they can handle. They'll be willing to pay you more and you'll have a steady income.
