Hi, this is a very competitive market and one where agents will compare prices between cleaners.
Should you produce a price list be sure to include what services are included in the price.
I would suggest that you do not give a comprehensive list of prices otherwise you leave yourself with no room to alter or negotiate prices should the property differ in size, be heavily soiled etc., but you might want to suggest the additional extras with or list them.
Another word of caution is that not all Estate Agents are sound!!!. This means that just because they set up on a high street does not mean that they will pay your bills on time. So be professional and ensure that you check them out. Do not create a huge credit line otherwise you might find yourself holding the can. Remember they can fold just as quickly as it takes for them to set up. THIS IS NOT TO PUT YOU OFF. Just a words of preventative actions. Make sure your contracts with them are sound and always have one in place outlining your terms and condition.
Hope this helps
