Here is a short list of summer jobs which you can create to generate income:
1. Learn calligraphy so that you can provide handwritten invitations and thank you notes to prospective wedding parties, birthday celebrations, etc. Seek out clients through wedding planners at nearby churches and temples. A starter calligraphy kit usually runs around $20 and anyone can easily pick up this skill. The going rate is usually $1 per hand addressed item.
2. Become a "poser" who assists wedding photographers in setting and arranging various individuals in group and single photographic positions. "Posers" carry around a sketch book of various sitting and standing poses which consists of onion skin overlays of various wedding pictures bound in albums. Again, contact local wedding photographers and wedding planners, accordingly. The hourly pay is around $10-$12 per hour and you are often invited to attend all dining activities.
3. Seek from your neighbors a gardner position which involves planting, weed removal, plant/tree trimming, light brush clearance. You will be using the neighbor's equipment and tools. Again, do not represent yourself as a lawn mower since there are any number of safety issues involved. A door-to-door solicitation of surrounding neighbors is required and you can charge between $6 to $9 per hour.
4. Offer policing/removal or clearance of trash services to surrounding neighbors which involve trash pickup within nearby residential area. Limit the extent of pickup to small areas and be aware that there are no hazardous terrain or elements involved in this process. Again, a door-to-door solicitation of neighbors is in order. You can charge between $6.75 to $7.50 per hour.
5. Acquire a set of window cleaning tools [a bucket, liquid window cleaner, sponge, squeegee, handle with an extension and a small step ladder] and solicit local businesses for your window cleaning services. However, be careful to limit the height of the window cleaning to no higher than one story. Charge $1 per window panel.
6. Become a proxy/stand-in for neighbors to allow delivery of goods and packages to your home/apartment. Acquire the authority to sign any receipt of incoming packages as an accepting neighbor. Charge $1 per each package handled by you.
7. Consider becoming a restaurant-cafe customer liaison by using your cell phone at restaurants-cafes to coordinate with the hostess to keep track of waiting customers. Whenever there's a very long period of time to activate a waiting list, you want to offer the restaurant your services so that customers do not have to stand around for any lengthy period of time. And when their name/assigned number comes up; you can call the upcoming customer's cell phone to tell them that they can return to the restaurant and be served. The call back fee is usually around $0.50 cents on a per head basis. For example, a couple would be charged $1.00 while children under 6 would not be charged. Placement of a plaque which outlines your fee schedule near the hostess station is sufficient to garner attention of prospective customers who will value your services since they can do other activities outside of the restaurant -- often beyond the range of any inhouse paging system. You realize that everyone has a cellphone and why not take advantage of the connectivity to make the diner's experience worthwhile. The restaurant will also appreciate the added service you are providing as a customer liaison.
Good luck!
